The HiiBot BlueFi is a microbit-compatible single board computer, but has enhanced computing ability, and connectivity. BlueFi uses Nordic nRF52840 (64MHz Cortex M4F, 1MB Flash and 256KB SRAM) as main processor, ESP32 (160MHz dual CPU, 4MB Flash and 520KB SRAM) as a co-processor. Features:
The HiiBot BlueFi have a lot of sensors, vs 6-DoF motion sensor of microbit, including 9-DoF motion sensors, sound sensor, temperature & humidity sensor, and integrated optical sensor. At the same time, BlueFi have two buttons, three touchpads, and 40-Pin extended interface on the microbit.
In a variety of IoT application scenario, BlueTooth and WiFi is an integral part of the wireless connection channel. BlueTooth and WiFi be supportted at the same time on the BlueFI board. You can realize bridges, gateways and other net equipment with BlueFi.
Built-in a lot of sensors and output devices on the HiiBot BlueFi, but a low-cost SBC. Our purpose is to help you quickly realize all kinds of ideas, no trouble wiring and welding electronic components.
The most exciting part of the HiiBot BlueFi is that while you can use it with the Arduino IDE - and it’s bonkers fast when you do, we are shipping it with CircuitPython on board. When you plug it in, it will show up as a very small disk drive with code.py on it. Edit code.py with your favorite text editor to build your project using Python, the most popular programming language. No installs, IDE or compiler needed, so you can use it on any computer, even ChromeBooks or computers you can’t install software on. When you’re done, unplug the BlueFi and your code will go with you.
Easy reprogramming: the HiiBot BlueFi comes pre-loaded with the UF2 bootloader, which looks like a USB storage key. Simply drag firmware on to program, no special tools or drivers needed! It can be used to load up CircuitPython or Arduino IDE.

This is the latest unstable release of CircuitPython that will work with the HiiBot BlueFi.
Unstable builds have the latest features but are more likely to have critical bugs.
Built-in modules available: _bleio, _pixelbuf, aesio, analogio, audiobusio, audiocore, audiomixer, audiomp3, audiopwmio, bitbangio, board, busio, digitalio, displayio, framebufferio, gamepad, math, microcontroller, neopixel_write, nvm, os, pulseio, pwmio, random, rgbmatrix, rotaryio, rtc, sdcardio, sharpdisplay, storage, struct, supervisor, terminalio, time, touchio, ulab, usb_hid, usb_midi, vectorio, watchdog
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.
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.
Latest version: 0.3.2
The bootloader allows you to load CircuitPython, Makecode, and Arduino programs. The bootloader is not CircuitPython. You can check the current version of your bootloader by looking in the INFO_UF2.TXT file when the BOOT drive is visible (FEATHERBOOT, CPLAYBOOT, etc.).
Updating the bootloader on nRF52840 boards is an involved process right now. Follow the instructions in this README. It is not necessary to update on each release if your bootloader is working fine. Read the release notes on GitHub to see what has been changed.
After you update, check INFO_UF2.TXT to verify that the bootloader version has been updated. Then you will need to reload CircuitPython.
