Image of Board

The Challenger RP2040 WiFi/BLE is an Arduino/Micropython compatible Adafruit Feather format micro controller board based on the Raspberry Pico chip, equipped with an WiFi/BLE chip that provides both WiFi as well as BLE functionality on the board.

RP2040 is the debut micro controller from Raspberry Pi. It brings their signature values of high performance, low cost, and ease of use to the micro controller space. With a large on-chip memory, symmetric dual-core processor complex, deterministic bus fabric, and rich peripheral set augmented with our unique Programmable I/O (PIO) subsystem, RP2040 provides professional users with unrivaled power and flexibility. With detailed documentation, a polished Circuitpython port, and a UF2 boot loader in ROM, it has the lowest possible barrier to entry for beginner and hobbyist users

The Challenger RP2040 WiFi/BLE board is equipped with a powerful combined single chip solution that provides the WiFi and BLE connectivity of this board. The chip we are using is the ESP32-C3FN4 from Espressif and it is a complete WiFi subsystem that complies with IEEE 802.11b/g/n protocol and supports Station mode, SoftAP mode, SoftAP + Station mode, and promiscuous mode. It also implements A Bluetooth LE subsystem that supports features of Bluetooth 5 and Bluetooth mesh.

This solution is based on an RISC-V micro controller core and comes with 4MByte of internal flash and 408Kbyte of internal SRAM as well as the advanced 2.4GHz radio.

The ESP32-C3 device comes pre loaded with the ESP-AT interpreter already programmed into flash. This interpreter provides the system with everything from low level TCP/UDP functionality up to high level functions such as a on board integrated web server, MQTT server and client functions and much more.

CircuitPython 8.0.0-beta.4

This is the latest unstable release of CircuitPython that will work with the Challenger RP2040 WiFi/BLE.

Unstable builds have the latest features but are more likely to have critical bugs.

Absolute Newest

Every time we commit new code to CircuitPython we automatically build binaries for each board and language. The binaries are stored on Amazon S3, organized by board, and then by language. Try them if you want the absolute latest and are feeling daring or want to see if a problem has been fixed.

Past Releases

All previous releases are listed on GitHub, with release notes, and are available for download from Amazon S3. They are handy for testing, but otherwise we recommend using the latest stable release. Some older GitHub release pages include the same binaries for downloading. But we have discontinued including binaries as assets on newer release pages because of the large number of files for each release.
