JHEMCU 8CH 3.3-20V 15mA SBUS UART PPM PWM Signal Conversion Module Converter for RC Airplane FPV Racing Drone

Read Before Buying:
1. The pins of the module are loose parts and have not been welded to the board. They need to be welded by yourself.If cannot accept,please place order carefully.
2. We do not provide encoding the UART serial port,and routines for decoding , and it is not recommended to purchase this module if there is no microcontroller programming level.
3.We do not accept after-sales issues such as returns and exchanges caused by customer's own program issues that result in cannot achieve functionality to question module quality issues. If cannot accept this question,please place order carefully.

Description:
- This module has powerful functions and can support any mutual conversion and seamless switching between the four signals of SBUS UART PPM PWM, without the need for any settings or choices, making it simple and convenient to use.

- High performance SPPU conversion module, with a wide voltage design that supports up to 20V input, uses a 32-bit microcontroller to complete signal acquisition, processing, and conversion. Its stability and speed are much higher than ordinary 8-bit microcontrollers. The input signal is automatically recognized without manual switching, plug and play, and the status indication is concise and clear. It supports 8-channel input/output (SBUS to UART, UART to SBUS is 16 channels). The UART serial port supports adjustable baud and frame rates, meeting the requirements of conventional MCU encoding and decoding.

Specification:

Brand: JHEMCU

Item: SBUS Signal Convert Module

Input voltage: 3.3-20V Current: 15MA Dimensions: 21*23MM Weight: 4.5 grams

Input Signal:
- PPM: CPPM
- PWM: for normal receiver signal
- SBUS: for futaba-R7008SB series,FrSky,etc
- UART: 35 bytes of serial input or output, with adjustable baud rate and frame rate, and can be encoded and decoded by other MCUs
- Regarding power supply: As long as the positions marked with VCC and GND on the board, power can be supplied and input, while other

empty VCCs can be synchronized output, and are actually interconnected inside the circuit board.

Purpose of UART:
- Due to the complexity of parsing and encoding of SBUS, it is resource intensive compared to conventional MCUs. Need to perform shift, concatenation, timeout judgment, packet loss identification, XOR verification operations, etc. This module handles these troublesome matters in advance, and provides a standard serial port to the end user. It only needs to a serial port receiving and sending to complete the encoding and decoding of SBUS signals.
- If your application scenario is wireless or long-distance wired communication, or it is required that data transmission must ensure accuracy,the integration of encoding and decoding is a good choice. Because standard SBUS does not have a verification mechanism, and wireless and long-distance communication are prone to data loss or bits errors. If there is no verification, the host will parse everything it receives. In case of incorrect data, it will be troublesome. Our module has a byte of check word, which the host can use to determine the accuracy of the data.

Function:
- Input SBUS signal while outputting UART, PPM, and PWM signals
- Input PWM signal while outputting UART, PPM, and SBUS signals
- Input PPM signal while outputting UART, PWM, and SBUS signals
- Input UART signal while outputting PPM, PWM, and SBUS signals

Indicator Light:
-When there is no signal input, all four indicator lights are on (PPM: green, SBUS: blue, PWM: red, UART: white)
-Input signal,the corresponding indicator light is constantly on, while the output signal indicator light is flashing
- For example, when inputting the SBUS signal, the corresponding blue indicator light of SBUS is always on, PWM red indicator light, SBUS blue indicator light and UART white indicator light are flashing.

Channel Description:
1-8 channels are PWM signal input or output channels
The SBUS channel is SBUS signals input or output channel
The PPM channel is PPM signal input or output channel
The T/R channel is UART signal input or output channel

Note:When welding, do not short circuit each other.
