Google Pigweed SDK now supports Raspberry Pi RP2350 microcontroller

Google Pigweed, a collection of open-source libraries for embedded software development, now supports the Raspberry Pi RP2350 MCU and comes as a software development kit (Google Pigweed SDK). These libraries, also called modules, are building blocks that make embedded software development faster and more reliable. It targets tiny 32-bit microcontrollers such as STMicro STM32L452, Nordic Semi nRF52832, and the Raspberry Pi Pico line of microcontrollers. The library components have shipped in Google Pixels, Nest thermostats, robots, satellites, and drones. On August 8, the Pigweed project was released as a software development kit (SDK) in developer preview with official support for Raspberry Pi RP2350 and the associated Pico 2 development board. The new release uses the Bazel build system – a feature upstreamed into the Pico SDK by the Google Pigweed team – and a complete, open-source Clang/LLVM toolchain. The Google Pigweed SDK includes sample code, modules, and a comprehensive tutorial […]

LILYGO T-TWR REV2.1 is an ESP32 walkie-talkie board with display, GNSS, and SA868 module

LILYGO has recently introduced an updated version of their T-TWR ESP32 walkie-talkie development board, the T-TWR REV2.1. This new board not only features Wi-Fi and Bluetooth but also has a GPS module for added functionality. Additionally, it has a new RF front-end matching circuit that can be configured to work with both VHF and UHF frequencies. The board is very versatile and can be programmed with Arduino IDE for various applications. The main difference between the older T-TWR and the newer T-TWR REV2.1 is that the new module has better power management with the AXP2102 single-cell Li-battery PWM charger, allowing it to use USB, a 21700 battery, or an 18650 battery, while the original T-TWR only supports USB and an 18650 battery. The new version also includes a GNSS module along with a microphone-switching matrix and a speaker-switching matrix for better sound quality. Additionally, the REV2.1 has the Push-To-Talk button […]

XIAO RP2350 is a tiny USB-C board based on Raspberry Pi RP2350 MCU

The XIAO RP2350 is an upgrade to Seeed Studio’s XIAO RP2040 board with a more powerful Raspberry Pi RP2350 dual-core Cortex-M33 or dual-core RISC-V microcontroller found in the just-launched Raspberry Pi Pico 2 board. The new Raspberry Pi RP2350 USB-C board has the same form factor but adds eight more GPIOs on the bottom with pads for a total of 19 GPIOs, and we lose two LEDs for serial port connectivity. Most people will still be fine with the XIAO RP2040, but if you need a more powerful microcontroller, extra memory, a few extra GPIOs, and built-in security, then the XIAO RP2350 will be an improvement. XIAO RP2350 specifications: Microcontroller – Raspberry Pi RP2350 MCU CPU – Dual-core Arm Cortex-M33 processor @ 150MHz (Note: again RISC-V is not mentioned at all by Seeed Studio, like for the Cytron MOTION 2350 Pro board) Memory – 520KB internal RAM 8KB OTP Storage […]
