This is the place to discuss all things pi-topPULSE. The pi-topPULSE is an official HAT and it can use Amazon Alexa as well!
The pi-topPULSE is different to our other add-ons.It doesnt have the Modular Rail Connector on both sides of the Add-On, and it also doesnt use all the pins. The table below shows which pins are used and for what.
| GPIO | Function |
|---|---|
| 0 | ID_SD |
| 1 | ID_SC |
| 2 | I2C_SDA |
| 3 | I2C_SCL |
| 14 | UART TXD |
| 15 | UART RXD |
| 18 | I2S_BCLK |
| 19 | I2S_LRCK |
| 21 | I2S_DOUT |
It’s a well documented piece of hardware with plenty of example code, so make sure to have a look on our Github Page:
