LattePanda 3 Delta SBC combines Jasper Lake processor and Arduino compatible microcontroller

The LattePanda 3 Delta single board computer with an Intel Celeron N5105 Jasper Lake processor and an Arduino ATmega32U4 Leonardo compatible MCU that initially launched through a Kickstarter campaign in November 2021. The team behind the board has now announced the global availability of the Intel + Arduino SBC on DFRobot starting at $279 plus shipping, which we can compare to the $229 pledge asked during the crowdfunding campaign for reference. LattePanda 3 Delta 864 specifications remain the same also with a few extra details: SoC – Intel Celeron N5105 quad-core Jasper Lake processor @ 2.0GHz / 2.9GHz (Turbo) with Intel UHD graphics 605 @ 450 to 800 MHz; 10W TDP System Memory – 8GB LPDDR4 @ 2933 MHz Storage 64GB eMMC 5.1 flash Support for M.2 NVMe or SATA SSD (See Expansion section) MicroSD card socket MCU – Microchip ATmega32U4-MU 8-bit AVR Arduino Leonardo compatible microcontroller Video Output HDMI […]

AquaPing is an open-source, battery powered acoustic water leak detector module (Crowdfunding)

The AquaPing is an open-source hardware, ultra-low power acoustic water leak detector sensor based on Texas Instruments MSP430 microcontroller and a microphone that can detect leaks without having to do any plumbing, instead capturing audio for water leak detection, and it even works for leaks behind walls. All signal processing and analysis occur on the MSP430 MCU, so no audio is streamed to the cloud and eavesdropping is impossible, plus the sensor only captures high frequencies out of the range of normal conversations, so eavesdropping is not feasible, plus those higher frequencies are also said to provide highest sensitivity and reliability. AquaPing specifications: MCU – Texas Instruments MSP430FR5994 microcontroller to perform FFT spectral analysis (10x faster/efficient than ARM-Cortex M0+) Audio capture – MEMS microphone covered by a small rectangular plastic structure to form a Helmholtz resonator. Minimum detectable leak rate – 0.01 gpm (gallon per minute) depending on stand-off distance […]

ESP32 board with rotary encoder gets 2-key keypad shield

LILYGO TTGO T-Encoder, a round-shaped ESP32 board with a built-in rotary encoder, has gotten a shield with a 2-key keypad based on WCH CH552 8-bit microcontroller. Launched several months ago, the TTGO T-Encoder is a USB-powered rotary encoder with ESP32 microcontroller offering WiFi and Bluetooth connectivity, and now, you can build a keypad with rotary encoder thanks to T-Encoder shield that features two mechanical switches and keycaps with RGB LED backlight. Since we missed it at launch, let’s check out the tiny TTGO T-Encoder board specifications first: System-in-Package (SiP) – Espressif ESP32-PICO-V3-02 with MCU – ESP32 Xtensa dual-core 32-bit Xtensa LX6 microcontroller up to 240 MHz, 448 KB ROM for booting and core functions, 520 KB SRAM for data and instructions, 2.4 GHz WiFi 4 and Bluetooth 4.2 BR/EDR + LE connectivity Memory – 2MB SPI PSRAM Storage – 8MB SPI flash Dimensions – 7×7 mm Antenna – Ceramic […]

$52 7.5-inch E-paper display connects to ESP32 boards

LILYGO 7-5 inch E-paper Display with T5 ESP32 board

So far LILYGO’s ESP32 boards with an E-Paper display such as the TTGO T5 or Mini E-Paper Core featured smaller displays from 1.02-inch to 2.9-inch. But the company is now offering a larger 7.5-inch display that works with most of its T5 boards excluding the one used with a 4.7-inch display. The black and white e-paper display offers a resolution of 800 x 480 pixels, is Arduino programmable and backward compatible with earlier T5 E-paper solution, and should be one of the most cost-effective to way to make a wireless E-paper display. LilyGO 7.5-inch E-paper display specifications: Panel SKU – DKE DEPG0750_U790F3 (See PDF datasheet. note non-secure link so your browser may complain) Size – 7.5-inch diagonal Resolution – 800 x 480 pixels (124 DPI) Active area – 163.2 x 97.92mm Pixel pitch – 0.204 x 0.204 mm Host interface – SPI Dimensions – 170.2 x 111.2 x 1.2 mm […]

T-Display-S3 board offers ESP32-S3 WiSoC, 1.9-inch color LCD, and LiPo battery support

LilyGO T-Display-S3 is an ESP32-S3 WiFi and Bluetooth LE IoT development board with a 1.9-inch color LCD and support for LiPo batteries that follows the company’s T-QT ESP32-S3 board with a tiny 0.85-inch display introduced earlier this month. The new board offers the same layout as the previous T-Display RP2040 or ES32 boards, but the 1.14-inch display has been replaced with a larger 1.9-inch display that covers most of the board, and thanks to the ESP32-S3 microcontroller, gains proper Bluetooth 5.0 support, as well as vector instructions for AI acceleration. T-Display-S3 specifications: Wireless MCU – Espressif Systems ESP32-S3R8 dual-core Tensilica LX7 @ up to 240 MHz with vector instructions for AI acceleration, 512KB RAM, 8MB PSRAM, wireless connectivity Storage – 16MB flash Connectivity via ESP32-S3 2.4 GHz 802.11 b/g/n Wi-Fi 4 with 40 MHz bandwidth support Bluetooth Low Energy (BLE) 5.0 connectivity with long-range support, up to 2Mbps data rate.

CANDuino v3 – A Microchip ATmega168PA board with CAN bus, Arduino Nano form factor

CANduino v3 is the third revision of MassiveButDynamic’s CAN bus board with Arduino Nano form factor based on Microchip ATmega168PA 8-bit AVR microcontroller, Microchip MCP2515 CAN controller with an SPI interface, and Microchip MCP2551 CAN transceiver suitable for 12V and 24V systems. The CANDuino v3 board is now slightly narrower in order to give access to two rows on each side when installed on a breadboard, comes with a USB Type-C port to reduce the number of cables needed, and the CAN bus function can be deactivated via a jumper in order to use the CANduino as a normal Arduino Nano. CANDuino v3 specifications: MCU – Microchip ATmega168PA 8-bit AVR microcontroller @ up to 16 MHz with 16KB flash, 512 bytes EEPROM, 1 KB SRAM CAN Bus CAN L/H header and CAN bus termination Microchip MCP2515 CAN controller connected to the AVR microcontroller over SPI. Supports CAN V2.0B at 1 […]

Arduino “launches” WisGate Edge LoRaWAN gateways in collaboration with RAKwireless

Arduino was already involved in LoRaWAN with its MKR WAN 1300 board, but now the company has started offering Arduino-branded Wisgate Edge Pro and Wisgate Edge Lite 2 LoRaWAN gateways for respectively outdoor and indoor environments as part of the Arduino Pro family. If the names of the gateways seem familiar, it’s because Arduino collaborated with Rakwireless, and is simply using their existing LoRaWAN gateways. As I understand it RAKwireless will provide the hardware and technical support, while Arduino will sell the gateways and other LoRaWAN hardware through its existing customer base, more acting as a distributor. Arduino WisGate Edge Lite 2 indoor gateway specifications: SoC – MediaTek MT7628 MIPS processor @ 580 MHz System Memory – 128MB DDR2 Storage OS on flash SD card for setup and diagnostics, backup, and data logging Connectivity 10/100M Ethernet RJ45 port 2.4 WiFi (802.11b/g/n) with -95 dBm RX sensitivity, 20dBm Tx power; internal […]
