Circuit Python at Noisebridge
Welcome to this page, which will get you started with Circuit Python. You can do this any time, or with a group at Circuit Hacking Monday
Some links to get started:
- If you are new to Circuit Python, start here! https://learn.adafruit.com/welcome-to-circuitpython/
- We are using the `Lolin S2 Mini` board. Here's some information: https://circuitpython.org/board/lolin_s2_mini/
- Todbot has some fun code to play with, like synthesizers! https://gist.github.com/todbot/
Tips and Tricks
To see the names of the pins available, enter the REPL (using Mu or a terminal program
import board dir(board)
For the LED library, pin 1 = IO1 and so forth...
It is possible that the silkscreen labels for pins 12 and 13 have been swapped. Test to make sure!

Installing Circuit Python on Lolin S2 Mini boards
We have already done this for you! But you might need to do it again, or if you get your own boards, this is how we do it.
- Install esptool.py from
- Download the latest Circuit Python binary from here:
- Put the Lolin S2 board into tty mode: while holding down RESET button, press and release the 0 button
- At the command line, enter
esptool.py -p /dev/ttyACM2 --chip esp32s2 --baud 1000000 write_flash -z 0x0 adafruit-circuitpython-lolin_s2_mini-en_US-8.0.0-beta.6.bin
(use the filename of the binary you just downloaded, it will be more recent than 8.0.0) - You can also do the previous step using [1], but only on Chrome browsers
- Reconnect your S2 Mini board, you should see a thumbdrive appear labeled <syntaxhighlight inline lang="css">CIRCUITPYTHON</syntaxhighlight>
- You are now able to edit code.py, add libraries to /lib, and connect to the serial port (usually /dev/ttyACM0 on Mac/Linux or COM3 on Windows
