# Board - 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 | | When SOFTSERIAL is enabled, LED_STRIP and CURRENT_METER are unavailable, but one SoftSerial port is made available to use instead. | Pin | Function | Notes | | --- | -------------- | -------------------------------- | | 7 | SOFTSERIAL1 RX | Enable `feature SOFTSERIAL` | | 8 | SOFTSERIAL1 TX | | ## Serial Ports | Value | Identifier | RX | TX | Notes | | ----- | ------------ | ---------- | ------------------ | ------------------------------------------------------------------------------------------- | | 1 | USART1 | RX / PA10 | TX / PA9 / TELEM | TELEM output is always inverted (for FrSky). Internally connected to USB port via CP2102 IC | | 2 | USART2 | RC4 / PA3 | RC3 / PA2 | | | 3 | USART3 | F3 / PB11 | F2 / PB10 | Flex port is configured as UART3 when port is configured | | 4 | SOFTSERIAL1 | RC5 / PA6 | RC6 / PA7 | |
