LilyGO T-PicoC3 board merges RP2040 & ESP32-C3, integrates color display

LilyGO T-PicoC3 is a small development board combining Raspberry Pi RP2040 dual-core microcontroller with ESP32-C3 RISC-V MCU to add WiFi and Bluetooth LE connectivity and adds a 1.14-inch color display to the mix, plus several I/Os. We had previously other designs merging ESP32 and RP2040 with UDOO KEY, Arduino Nano RP2040 Connect, or the Pico Wireless Pack among others, but as far as I know, the T-PicoC3 board is the first to use Raspberry Pi RP2040 and ESP32-C3 RISC-V processor. LilyGO T-Pico3 specifications: Microcontrollers Raspberry Pi RP2040 dual-core Cortex-M0+ MCU with 264 KB of embedded SRAM Espressif Systems ESP32-C3 RISC-V processor with WiFi 4 and Bluetooth 5.0 LE connectivity Storage – 4MB SPI flash connected to RP2040 Display – 1.14-inch full-color IPS LCD Display (ST7789V SPI controller) with 240 x 135 resolution USB – USB Type-C port for power and programming (RP2040 / ESP32-C3) Expansion – 15-pin + 12-pin expansion […]

Android RISC-V progress update, emulator support, and roadmap to 2023

We’ve first covered Alibaba T-Head work on Android 10 for RISC-V in January 2021, and later that year they started selling the T-Head RVB-ICE dual-core RISC-V board with GPU for software development. The company has now provided an update for Android 12 RISC-V port, instructions to build Android RISC-V to run it in an emulator,  as well as a 2022-2023 roadmap. Alibaba T-head is working on hardware platforms, which appears to be similar to T-Head RVB-ICE board, with the following minimal specifications: CPU – At least Dual-core XuanTie C910 (rv64imafdcv) processor GPU – Compatible with OpenGL ES and OpenCL VPU – HW Video/Picture codec Neural Network Accelerator System Memory – 4GB or more DDR Memory Display – MIPI/HDMI Audio – Multi-Channel Audio output & input Camera – ISP with support for multiple MIPI CSI lanes USB interface(s) They built upon the work done on Android 10 to add support for […]

$10 T-Zigbee board combines ESP32-C3 and TLSR8258 for Zigbee 3.0, WIFi and BLE connectivity

LilyGO T-Zigbee board combines ESP32-C3 WiFi and BLE wireless microcontroller and Telink TLSR8258 multi-protocol wireless SoC compatible with BLE 5 Mesh, Zigbee, RF4CE, Thread, 6LoWPAN, HomeKit, ANT, and 2.4GHz proprietary standards. As I understand it, T-Zigbee is designed to act as a Zigbee to WiFi bridge, and is compatible with Zigbee2MQTT and Home Assistant, allowing easy integration into your home automation setup. Based on the hardware, I’d assume it may be usable as a BLE to MQTT gateway as well, in a fashion similar to GL.inet GL-S10 gateway, for people willing to work on the software/firmware. T-Zigbee specifications: Wireless MCUs Espressif Systems ESP32-C3 RISC-V processor with WiFi 4 and Bluetooth 5.0 LE connectivity Telink Semiconductors TLSR8258 (PDF product brief) Arm Cortex-M0 multiprotocol microcontroller @ 48 MHz with BLE 5 Mesh, Zigbee, RF4CE, Thread, 6LoWPAN, HomeKit, ANT, and 2.4GHz proprietary connectivity Antennas – 2x PCB antennas, 2x u.FL antenna connectors USB […]

Axzez Interceptor carrier board for RPi CM4 gets 8-port PoE+ board

The features-rich Axzez Interceptor carrier board for Raspberry Pi CM4 has gotten the Interceptor PoE board with eight PoE+ ports for connecting up to sixteen PoE IP cameras making it usable as a network video recorder. We first wrote about the Interceptor last January noting its impressive I/O capabilities with five SATA ports, four Gigabit Ethernet, two HDMI ports, RS-485 terminal block, and more. It also had two 40-pin FFC connectors “for future expansion”. Those connectors have now found a “meaning to life” with the Interceptor PoE board, as up to two can be connected to the FFC connectors. Some of the features of the new Interceptor PoE Board include: 8x fast PoE+ ethernet ports IEEE 802.3AF-2003 and 802.3AT-2009 compliance Each port has activity/link and status LEDs Input voltage range – 44-57V Optional 48V power boost that can support up to two Interceptor PoE+ boards (Powered from 12V ATX power […]

Home Assistant gives new life to Insteon Smart Home products following Smartlabs bankruptcy

Smartlabs used to sell Insteon Smart Home products, but the company is now in bankruptcy proceedings, its cloud has been turned off, and users have reported their products not working since April 14. Going to Insteon website confirms the problem: …the company engaged in a sales process in November, 2021. The goal was to find a parent for the company and continue to invest in new products and the technology. The process resulted in several interested parties and a sale was expected to be realized in the March timeframe. Unfortunately, that sale did not materialize. Consequently, the company was assigned to a financial services firm in March to optimize the assets of the company. IoT and Smart Home products going offline are nothing new, either because the company is going bankrupt or the product is not profitable anymore. It happens to me with Weloop Hey 3S smartwatch which I still […]
