Paris Air Hero 32 / Acro Naze 32 Mini
This board uses the same firmware as the Naze32 board.
Sensors
MPU6500 via SPI interface.
Ports
6 x 3pin ESC / Servo outputs 1 x 8pin JST connector (PPM/PWM/UART2) 1 x 4pin JST connector (UART3/I2C)
Pinouts
The 10 pin RC I/O connector has the following pinouts when used in RX_PPM/RX_SERIAL mode.
From right to left when looking at the socket from the edge of the board.
| Pin | Function | Notes |
|---|---|---|
| 1 | Ground | |
| 2 | +5V | |
| 3 | RX_PPM | Enable feature RX_PPM |
| 4 | RSSI_ADC | Enable feature RSSI_ADC. Connect to the output of a PWM-RSSI conditioner, 0v-3.3v input |
| 5 | USART2 TX | |
| 6 | USART2 RX | Built-in inverter |
| 7 | LED_STRIP | Enable feature LED_STRIP |
| 8 | unused |
