## Description

8-channel signal converter for quick integration between receivers and controllers, automatically converts SPP PPM PWM and SBUS without manual settings. Operates on wide 3.3-20V power supply, 32-bit microcontroller for stability and fast response, simultaneous conversions between formats, status LEDs for immediate signal identification and easy troubleshooting.
The SPP conversion module from JHEMCU, for converting multiple signals. With a wide voltage design up to 20V and a 32-bit microcontroller, this converter ensures superior stability and speed compared to 8-bit microcontrollers, automatically recognizing input signals. It is ideal for systems that require fast and safe conversion of PPM, PWM and SBUS signals, being suitable for a wide range of applications due to its compatibility with different types of receivers.
Provides LED indicator for quick viewing of signal used or no signal, for quick troubleshooting.
Technical specifications:
Brand: JHEMCU
Input voltage: 3.3-20V
Current: 15 mA
Dimensions: 21 x 21 mm
Weight: 4.1 g
Channels: 8 channels (I/O)
Accepted input signals:
PPM (CPPM): Common receiver control signal
PWM: Standard signal for receivers
SBUS: Compatible with R7008SB series, FrSky, etc.
Functions:
Automatic Signal Conversion: Automatic recognition of the input signal for conversion without manual switching.
Multiple Simultaneous Conversions:
SBUS signal input → PWM and PPM signal output
PWM signal input → PPM and SBUS signal output
PPM signal input → PWM and SBUS signal output
Signal LED indicator: Each signal has a dedicated indicator:
When there is no input signal, all three indicators (PPM - green, SBUS - blue, PWM - red) are lit.
The indicator of the input signal flashes, and that of the output signal remains lit constantly, providing an easy visual monitoring of the device's status.
Channels:
Channels 1-8: Accept PWM signals as input or output
SBUS channel: Accept SBUS signal as input or output
PPM Channel: Accept PPM signal as input or output
Wiring instructions:
PWM input: Channels 1-8 as PWM input → Output on PPM channel and SBUS channel.
PPM input: PPM channel as input → PWM output on channels 1-8 and SBUS output.
SBUS input: SBUS channel as input → PWM output on channels 1-8 and PPM output.
