Pinout
We don't publish a pin table for this part: no official source we could verify gives one. Check the labels printed on your module, and see the notes below.
FlySky's current FS-TH9X specifications list 8 channels with AFHDS 2A; if your unit's manual or box shows a different channel count or protocol, follow your manual.
Build with it
Project ideas for the FlySky FS-TH9X transmitter. Each link opens Soldr with the prompt filled in; Soldr assigns the pins, checks power and shows how to wire every part.
- Stick monitor: Both parts are AFHDS 2A per their maker pages. The receiver runs from the Uno's 5 V pin (4.0 V to 6.5 V range); the maker gives no output signal level, so measure it before using a 3.3 V board. Bench only, no motors connected. Learning project.
- PPM channel viewer: The iA6B maker page lists AFHDS 2A, a 4.0 V to 8.4 V supply and PPM among its data ports, so the Uno's 5 V pin can power it. The maker gives no output signal level; measure it before connecting. Bench only, no motors connected. Learning project.
- Compact PPM monitor: The iA6B page lists AFHDS 2A, 4.0 V to 8.4 V supply and PPM output; the Nano's 5 V pin is inside that range. The maker gives no output signal level; measure it first. Bench only, no motors connected. Learning project.
Common mistakes
- Plugging in a charger. The maker lists the charging port as N/A, so it is built for 8 AA cells (source: link, Specifications).
- Pairing it with a receiver on another protocol. The maker names AFHDS 2A (source: link, Specifications).
- Counting on nine channels. The maker lists 8 channels (source: link, Specifications).
Not covered by the official source
- The maker page lists no current draw, binding steps or pin table for the phone jack.
- Ideas stay on bench pulse reading because no output signal levels are documented.
