Nano 33 IoT board
1. This sketch uses HTML form to get and process commands from external browser applications to configure the
FM transmitter based on QN8066.
Nano 33 IoT Wire up
| Device name | QN8066 Pin | Nano 33 IoT |
| --------------------------| -------------------- | ----------------- |
| QN8066 | | |
| | VCC | 3.3V |
| | GND | GND |
| | SDIO / SDA (pin 2) | A4 |
| | SCLK (pin 1) | A5 |
| --------------------------| ---------------------| ----------------- |
| PWM Power Controller [1] | | |
