## Purchase Channels

## 무선 조종

A Radio Control (RC) system is required if you want to manually control your vehicle (PX4 does not require a radio system for autonomous flight modes).

기체와 조종자가 통신하기 위하여 송신기와 수신기를 바인딩하여야 합니다.
송신기와 수신기의 매뉴얼을 참고하십시오.

Spektrum/DSM receivers connect to the DSM/SBUS RC input.
PPM or SBUS receivers connect to the RC IN input port.
CRSF receiver must be wired to a spare port (UART) on the Flight Controller. Then you can bind the transmitter and receiver together.

## 시리얼 포트 매핑

| UART   | 장치         | 포트       |
| ------ | ---------- | -------- |
| USART1 | /dev/ttyS0 | GPS      |
| USART2 | /dev/ttyS1 | TELEM3   |
| USART3 | /dev/ttyS2 | 디버그 콘솔   |
| UART4  | /dev/ttyS3 | UART4    |
| UART5  | /dev/ttyS4 | TELEM2   |
| USART6 | /dev/ttyS5 | PX4IO/RC |
| UART7  | /dev/ttyS6 | TELEM1   |
| UART8  | /dev/ttyS7 | GPS2     |

## PWM Output

The E2-Plus flight controller supports up to 14 PWM outputs.
The first 8 outputs (labelled M1 to M8) are controlled by a dedicated STM32F103 IOMCU controller.
The remaining 6 outputs (labelled 9 to 14) are the "auxiliary" outputs.
These are directly attached to the STM32H753 FMU controller .

The 14 PWM outputs are:

M1 - M8 are connected to the IOMCU
A1 - A6 are connected to the FMU

M1 - M8 support DShot and are in 3 groups:

- M1, M2 in group 1
- M3, M4 in group 2
- M5, M6, M7, M8 in group 3

The 6 FMU PWM outputs are in 2 groups:

A1 - A4 are in one group.
A5, A6 are in a 2nd group.

Channels within the same group need to use the same output rate.
If any channel in a group uses DShot then all channels in the group need to use DShot.

### Electrical data

- Voltage Ratings:
  - Max input voltage: 5.7V
  - USB Power Input: 4.75\~5.25V
  - Servo Rail Input: 0\~9.9V
- Current Ratings:
  - TELEM1 and GPS2 combined output current limiter: 1.5A
  - All other port combined output current limiter: 1.5A

## Battery Monitoring

The board has connectors for 3 power monitors.

- POWER1 -- ADC
- POWER2 -- DroneCAN
- POWER3 -- I2C

The board is configure by default for a analog power monitor, and also has DroneCAN power monitor and I2C defaults configured which is enabled.

The default PDB included with the E2+ is analog and must be connected to `POWER1`.

- [PX4 System Console](../debug/system_console.md) (Note, the FMU console maps to USART3).
- All ports use GH1.25 ,power ports use ports on E2 uses the 6 circuit [2.00mm Pitch CLIK-Mate Wire-to-Board PCB Receptacle](https://www.molex.com/en-us/products/part-detail/5024430670).
