Hi I have received a Keybow Mini and I’m looking to interface with it.
The board mentions i2c and SPI.
Wondering if there is any refence as to how I can connect to it with microcontroller.
Specifically I want to use i2C
Any help would be appreciated.
On the board that plugs into the Pi, there is a black header that accepts male DuPont jumper wires. What pin does what will be silkscreened to the other side on that board.
The pictures aren’t the best but if you look closely you’ll see it.
The pins used for i2c are as follows
I2C at Raspberry Pi GPIO Pinout
And SPI is as follows
SPI at Raspberry Pi GPIO Pinout
Check the labeling to see if its SPI0 or SPI1, more than likely SPI0.
And if it uses CE0 or CE1.
One wrinkle may be that it uses Circuit Python, not Micro Python.
Pimoroni uses Micro Python, while Adafruit uses Circuit Python.
What device do you want to connect via i2c?
Either Trinkey RP2040 QT
or
QT PY SAMD
The keybow mini doesn’t respond to i2c via the pin connector header- methinks it is potentially flashed to work off SPI
no further documentation seems to be provided
