Raspberry Pi RP2040 gets into BBC Micro:bit lookalike board

Raspberry Pi RP2040 BBC Micro:bit board

ELECFREAKS Pico:ed V2 is a Raspberry Pi RP2040 board heavily inspired by the BBC Micro:bit with an edge connector exposing rings suitable for crocodile clips, a 17×7 LED matrix display, and designed for the classroom. We’ve seen several BBC Micro:bit clones – or rather adaptations – over the years with boards such as the SiFive Learn Inventor, Elecrow Mbits, and  HiHope “Big Brother” board. The Pico:ed V2 adds to the list, and the main differences are that it is based on the Raspberry Pi RP2040 microcontroller instead, and does not come with wireless connectivity relying on a USB interface only. ELECFREAKS Pico:ed V2 specifications: MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ up to 133Mhz with 264kB of SRAM Storage – 2MB QSPI flash Display – 17×7 dot-matrix display USB – 1x micro USB 1.1 port for power, data, and programming I/Os 25-pin notched “Wavy” connector with up to […]

LiLyGo T-SIMCAM ESP32-S3 camera development board supports optional 4G LTE connectivity

ESP32-S3 has been in the news recently and we just wrote about the Bee S3 and BPI-PicoW-S3 boards yesterday, but there’s more, and LilyGo T-SIMCAM ESP32-S3 is another interesting ESP32-S3 board with a 2MP camera as well as support for an optional 4G LTE module. The board can make use of the AI capabilities from the ESP32-S3 microcontroller through the built-in camera and microphone and offers two options for power with 5V through a USB Type-C port, as well as a 2-pin JST connector for connecting a battery.

$5.5 Banana Pi BPI-PicoW-S3 ESP32-S3 board follows Raspberry Pi Pico W form factor

Banana Pi’s BPI-PicoW-S3 is a development board following the Raspberry Pi Pico W form factor, but based on Espressif System ESP32-S3 dual-core microcontroller offering both WiFi 4 and Bluetooth LE connectivity. The Raspberry Pi SBCs have inspired many designs, but the Raspberry Pi Pico MCU boards less so. So far, I had only seen the WeAct RP2040 board with the same layout except for a USB Type-C port and a 16MB flash. But the Banana Pi BPI-PicoW-S3 provides a direct alternative to the Raspberry Pi Pico W with a more powerful microcontroller, vector instructions for AI acceleration, BLE, and about the same price at $5.5 plus shipping. Let’s see how the BPI-PicoW-S3 specifications compare to the ones of the Raspberry Pi Pico W in the table below. While the power signal (5V, 3.3V, GND) and GPIO numbers are the same on both boards, there are a few variations here and […]

OpenHarmony development board borrows BBC Micro:bit edge connector

HopeRun’s HiHope development board features a HiSilicon Hi3861V100 32-bit RISC-V microcontroller compatible with OpenHarmony OS and looks very much like the BBC Micro:bit educational board notably with its edge connector. The board is also designed for youth education (in China) and comes with similar sensors, but there are some differences such as a 0.96-inch OLED instead of an LED matrix and support for offline voice recognition. There’s no wireless connectivity apart from NFC support. HiHope board specifications: MCU – HiSilicon Hi3861 32-bit microcontroller @ up to 160 MHz with 352 KB SRAM and 288 KB ROM, 2 MB flash memory Display – 0.96-inch OLED display with 128×64 resolution (SSD1306) Connectivity – NFC with R/W mode, card emulation,  and bidirectional mode USB – 1x USB Type-C port for power and programming Sensors – Temperature & humidity sensor, light sensor, microphone, 6-axis motion sensor Expansion – Edge connector with 5x rings (3x […]
