RP2040 FlexiBoard is a bendable Raspberry Pi Pico clone made of flexible PCB (Crowdfunding)

[Update December 22: The project was previously called FlexiPi, but Raspberry Pi considered it infringed on its trademarks, so the name was changed to RP2040 FlexiBoard instead]. RP2040 FlexiBoard is a bendable Raspberry Pi RP2040 board made of flexible PCB with the same layout as the original Raspberry Pi Pico, but featuring a USB-C port instead of a micro USB port on the official board. This follows the Flexduino flex PCB clone of the Arduino UNO made by “EDISON SCIENCE CORNER”, but the smaller design of “TOP Gadgets” RP2040 FlexiBoard may make it potentially more useful since it could be inserted into tight or round enclosures. RP2040 FlexiBoard specifications: MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ 48 MHz (overclockable to 133 MHz) with 264KB SRAM Storage – 2MB QSPI flash USB – 1x USB Type-C 1.1 port used for power and programming Expansion 2x 20-pin 2.54mm pitch header […]

XIAO ESP32S3 for Meshtastic & LoRa devkit features Wio-SX1262 LoRa module

The “XIAO ESP32S3 for Meshtastic & LoRa” is an ESP32-S3 LoRa dev kit that combines an XIAO ESP32S3 board with the tiny Wio-SX1262 LoRa module connected through a board-to-board connector. This compact devkit supports LoRa (862-930MHz), Wi-Fi (2.4GHz), and Bluetooth 5.0 (BLE), with a 5km range for LoRa and a 100m+ range for Wi-Fi/BLE. The kit also has a USB Type-C interface, a built-in power management chip, and multiple I/O options such as IIC, UART, and GPIO. It supports external LoRa antennas and can be extended with XIAO expansion boards for more complex setups. These features make this device suitable for projects such as LoRaWAN gateways, IoT sensors, Meshtastic nodes or routers, and applications where space is limited. XIAO ESP32S3 for Meshtastic & LoRa specifications: SoC – Espressif Systems ESP32 with dual-core Xtensa LX7 microcontroller up to 240MHz Wireless Connectivity LoRaWAN via Semtech LX1262 Output Power – Up to +22 […]

Wiznet W55RP20-EVB-Pico board features W55RP20 SiP with W5500 Ethernet controller and RP2040 MCU

Wiznet has recently released the W55RP20-EVB-Pico dev board, a compact board based around the W55RP20 SiP that fuses the Raspberry Pi RP2040 MCU and the W5500 Ethernet controller into a single IC, plus a 2MB flash chip for firmware storage. Just last month we wrote about W5100S-EVB-Pico2 and W5500-EVB-Pico2 dev boards, both the boards have a newer Raspberry Pi RP2350 MCU and external Ethernet controller (W5500 or W5100S). The RP2350 offers additional security features such as One Time Programmable (OTP) memory, secure boot, and Arm TrustZone technology, making it more suitable for secure applications. The W55RP20 on the other hand integrates a W5500 Ethernet controller and the RP2040 in a single SiP which is also pin-compatible with the Raspberry Pi Pico, making it easy to use existing Pico accessories and code examples. W55RP20-EVB-Pico dev board specifications: SiP– W55RP20 microcontroller MCU – Raspberry Pi RP2040 Core– Dual Cortex M0+ cores up […]

Arduino Nicla Sense Env module features temperature, humidity, and gas sensors from Renesas

Arduino Nicla Sense Env is a new sensor module with temperature, humidity, and gas (TVOC, NO2, O3) sensing that follows the launch of the Arduino Nicla Sense ME (Motion & Environment) module over three years ago (2021). The implementation of the new module is quite different since the ME module relies on Nordic Semi nRF52832 Cortex-M4 microcontroller and Bosch SensorTech motion and environmental sensor, but the new Nicla Sense Env module is made of parts from Renesas namely the RA2E1 Cortex-M23 microcontroller, the HS4001 humidity and temperature sensor, the ZMOD4410 gas sensor for TVOC and indoor air quality, and the ZMOD4510 gas sensor for NO2, O3, and outdoor air quality. Arduino Nicla Sense Env (ABX00089) specifications: MCU – Renesas RA2E1 Arm Cortex-M23 entry-line microcontroller (not accessible or programmable by the user) CPU core – Arm Cortex-M23 core up to 48 MHz Memory – 16KB SRAM Storage – 128KB flash Sensors […]

Flipper Zero hacking tool gets MicroPython support

Developer and engineer Oliver Fabel has developed a port that is designed to run MicroPython on the Flipper Zero. This port allows users to write programs for Flipper Zero in Python, instead of built-in JavaScript. Till now you can access GPIO, ADC, PWM, the speaker, buttons, the display, and infrared communication with this but it doesn’t have support for NFC or RFID yet, and it’s still under development. Previously we have written about various addon boards for the Flipper Zero like the Mayhem v2, the ESP8266 Deauther board, the CAN bus addon board, and other powerful alternatives of the Flipper like The M1 and the HackBat. Feel free to check those out if you are interested in the topic. The process is simple, and you don’t have to do a firmware update to work with MicroPython, you can download the application from the community-driven Flipper app store and are good […]

Pimoroni Pico Plus 2 W combines RP2350B MCU with Raspberry Pi RM2 Wi-Fi and Bluetooth module

Raspberry Pi released the Raspberry Pi Pico 2 a few months ago, featuring the new RP2350 chip. Despite several upgrades, it lacks wireless connectivity like Pico W. While there’s no official Raspberry Pi Pico 2 W yet, Pimoroni has developed an unofficial alternative, the Pimoroni Pico Plus 2 W, which integrates Wi-Fi and Bluetooth using a yet-to-be-formally-announced Raspberry Pi RM2 module and potentially set to appear in a future Pico 2W. The Pimoroni Pico Plus 2W board is powered by the Raspberry Pi RP2350B dual-core Arm Cortex-M33 microcontroller, features 16MB of QSPI flash with XiP support, 8MB of PSRAM, wireless connectivity, a USB Type-C port for power and data, and a Qwiic/STEMMA QT connector for breakout board integration. A few days ago, we covered the Pimoroni Explorer board, an electronic prototyping board built around the Raspberry Pi RP2350B chip. It features a 2.8-inch LCD screen, a speaker connector, and multiple […]

M5Stack ESP32-S3-Pico-based devkits: ATOMS3R with 0.85-inch color display, and ATOMS3R Cam with VGA camera

M5Stack ATOMS3R and ATOMS3R Cam are two tiny devkits based on ESP32-S3-Pico system-in-package and a similar design but the first one features a 0.85-inch color color IPS display, while the other is equipped with a GC0308 VGA camera. Both modules measure just 24x24mm with a thickness of around 13mm, integrate BMM150 and BMI270 motion sensors, offer GPIO expansion through female headers and a grove connector, and feature an infrared transmitter and a USB Type-C port for power and programming. Those are the second devkits based on the ESP32-S3-Pico SiP after we covered the tiny OMGS3 module earlier this week. M5Stack ATOMS3R with display ATOMS3R specifications: SiP – Espressif ESP32-S3-PICO-1-N8R8 SoC ESP32-S3 dual-core Tensilica LX7 up to 240 MHz with 512KB SRAM, 16 KB RTC SRAM Wireless – WiFi 4 and Bluetooth 5 LE + Mesh Memory – 8MB QSPI PSRAM Storage – 8MB QSPI flash Display – 0.85-inch color IPS screen […]
