Tangara is a portable music player that is out to make MP3 players cool again. With an iPod-inspired design and an ESP32 module at its core, Tangara presents an open-source and nostalgic way to listen to your favorite music and podcasts. The ESP32-WROVER-E at the core of the music player is the main microcontroller but it also features a co-processor, a Microchip SAMD21, which is responsible for USB communication and power management. We have covered the ESP32-WROVER-KIT, a development kit for the ESP32-WROVER and ESP-WROOM-32 line of modules with a JTAG interface and an LCD. The Tangara music player can output audio through a 3.5mm headphone jack or Bluetooth, although Bluetooth is currently limited to the default SBC codec. Tangara is the brainchild of Australian tech company Cool Tech Zone and is aimed at the portable media player community at large. This is reflected in many of the design choices […]

EVN Alpha is a LEGO-compatible robotics controller built around Raspberry Pi RP2040 MCU (Crowdfunding)

EVN ALPHA Raspberry Pi RP2040 Robot

The EVN Alpha is a robotics project from a team based in Singapore and is aimed at roboticists seeking an advanced building platform beyond what LEGO Robotics kits offer. This robotics controller can be considered a spiritual successor to the LEGO MINDSTORMS EV3 intelligent brick. It runs on the Raspberry Pi RP2040 microcontroller with two Cortex M0+ cores running at a maximum clock speed of 133 MHz and 264KB of embedded SRAM and builds upon the rich software support available for the microcontroller. It features 64 LEGO Technic-compatible holes on five sides for easy installation into your projects and has 26 ports for I2C, UART, servos, EV3, and NXT motors. It is smaller volumetrically than the LEGO bricks and can be powered from two generic 18650 Lithium-ion cells rather than a proprietary solution (unlike the LEGO SPIKE Prime). The EVN Alpha was created as a “basecamp for students looking to […]

Lichee Console 4A RISC-V devkit testing – Part 2: benchmarks and features in Debian 12

Sipeed Lichee Console 4A RISC-V devkit review

When checking out the hardware of the Lichee Console 4A portable RISC-V development terminal in the first part of the review, I noted that I had some troubles with the display that did not work properly. I did a little massage to “fix” the display, but unsurprisingly it ended up not being a long-term solution. So I had to open a case a few times and ended up breaking the wires to the fan… Each time I reassembled the device, the display only worked for a few seconds or minutes if at all. So I decided to test the system by keeping it open, as the display is working reliably that way. So I won’t be able to do a proper review testing the device on the go, but I still tested all features and benchmarked the T-Head TH1520 mini laptop with Debian 12, and will report my findings in […]

Nordic’s nRF9161 SiP and DK support cellular IoT and DECT NR+ non-cellular 5G technology

Nordic nRF9161 SiP and Development Kit

Nordic Semiconductor recently announced the availability of the nRF9161 system in package (SiP) and pre-certified Development Kit designed to power both cellular IoT and non-cellular 5G technologies. This new device can connect to LTE-M, NB-IoT, and DECT NR+ networks while maintaining long battery life, better location tracking, and strong connectivity. Additionally, Nordic offers support through their nRF Connect SDK and the Nordic Developer Academy. The nRF9161 SiP is an improved version of the nRF9160 SiP, which has been the basis for various projects like the Actinius Icarus SoM DK, Conexio Stratus, nRF9160 Feather LTE IoT and GPS Board,  Ruuvi Node, and many other projects. Feel free to check those out if interested. The press release mentions that this new chip is an update of the nRF9160 and includes features like an Arm Cortex-M33 processor, 1 MB flash, 256 KB RAM, along with SPI, I2C, UART, PWM, and a 12-bit ADC […]

Renesas releases the DA14592, a new dual-core Cortex-M33/M0+ BLE chip with integrated flash

DA14592 chip block diagram

The DA14592 System-on-Chip (Soc) is Renesas’ “lowest power consumption and smallest, multi-core Bluetooth LE device.” According to the company, this chip’s design was achieved by making careful tradeoffs between on-chip memory and die size. The chip offers an ultra-low power mode that uses only 2.3mA when transmitting radio signals at 0dBm and consumes 1.2mA to receive radio signals. It also supports a hibernation mode that uses about 90nA and can extend the operating life of battery-powered products. The active mode is best for processing-intensive products and uses 34µA for every MHz of CPU clock. Projected key applications for the DA14592 chip include crowd-sourced location (CSL) tracking as used in Apple’s Airtags, remote control units, human interface devices, asset tracking, IoT end nodes, data logging, connected health, and activity tracking. Renesas DA14592 specifications: CPU cores: Cortex-M33F running at up to 64MHz as application core Cortex-M0+ at 64MHz as configurable MAC Memory: […]

Renesas RZ/G3S is a 64-bit Arm Cortex-A55/M33 microprocessor with low power consumption and enhanced peripherals

rzg3s lineup en

Renesas RZ/G3S 64-bit Arm Cortex-A55 microprocessor (MPU) designed for IoT edge and gateway devices consumes as little as 10µW in standby mode thanks to its Cortex-M33 core(s) and features a PCIe interface for high-speed data transfers with 5G wireless modules. A single-core ARM Cortex-A55 CPU powers the RZ/G3s and can distribute workloads to two sub-CPUs, boosting efficiency in task handling and resulting in fewer components and a smaller system size. The Cortex-A55 core operates at 1.1GHz and is designed to improve power efficiency and performance over its predecessor, the Cortex-A53. The RZ/G3S isn’t Renasas’ first Cortex-A55 product as they have previously released the RZ/A3UL and the RZ/G2L, both powered by the same Cortex-A55 CPU. Additionally, Renesas launched the 64-bit RISC-V RZ/Five processor late last year. The RZ/G3S boasts high-speed interfaces such as PCIe and GbE, a better standby mode, and improved security features which make it suitable for IoT applications […]

Renesas RA8D1 Arm Cortex-M85 SoC features LCD display interfaces, 2D graphics accelerator

Renesas RA8D1

Renesas RA8D1 is a new Arm Cortex-M85 microcontroller with graphics capabilities such as a 2D graphics accelerator and MIPI DSI and parallel RGB interfaces to connect an LCD that will make the chip suitable for HMI applications. Renesas introduced the world’s first Arm Cortex-M85 microcontroller with the RA8M1 just a few weeks ago, but the MCU has limited multimedia capabilities with just a 16-bit Capture Engine Unit (CEU) interface to connect a camera. The second member of the Renesas RA8 family fills this void with the RA8D1 microcontroller adding an LCD controller and a 2D graphics drawing engine on top of the CEU camera interface. Renesas RA8D1 specifications: MCU core – Arm Cortex-M85 clocked at 480 MHz with Helium MVE (M-Profile Vector Extension) with 32KB I/D caches, 12KB data flash Memory & Storage 1MB SRAM with TCM (128KB) 1MB to 2MB Flash memory 32-bit external SDRAM interface Display interfaces and […]

Lite3DP Gen 2 is a tiny, open-source resin 3D printer (Crowdfunding)

lite3dp gen 2 resin printer

The Lite3DP Gen 2 3D Printer builds on the success of its predecessor. With a new and improved design, an ESP32 microcontroller replacing the Arduino Pro Mini, and several other improvements, the Lite3DP Gen 2 is well-suited for making small, detailed resin prints. It is slightly bulkier than the Lite 3DP S1 3D printer but is still compact enough to fit into a bag. Gen 2 has been designed to maintain backward compatibility with the older model, and owners of existing Lite3DP printers can use the Gen 2 dev kit to upgrade their printers. The resin 3D printer is completely open-source (firmware, hardware, and software), and you can use the schematics, Gerber files, code, and other resources hosted in the GitHub repository to build a different kind of mSLA resin printer. Lite3DP Gen 2 key features & specifications: Electronics – All-in-one PCB with ESP32 microcontroller, high-res LCD, an ultra-silent TMC2209 […]
