## 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.

The maker's page gives no pin table for the receiver.

## Build with it
Project ideas for the FlySky FS-R6B receiver. Each link opens Soldr with the prompt filled in; Soldr assigns the pins, checks power and shows how to wire every part.

- [Channel pulse display](https://app.soldr.ai/?prompt=I%20want%20to%20build%20a%20radio%20channel%20pulse%20display%20that%20reads%20an%20RC%20receiver%20and%20shows%20the%20pulse%20widths%20on%20an%20OLED%20with%20an%20Arduino%20Uno): The Uno's 5 V pin is inside the receiver's 4.0 V to 6.5 V range and the sketch times the PWM pulse on each input. The maker page gives no signal voltage level for the receiver output pins; measure it with a multimeter before connecting it to any 3.3 V board. Learning project. Pair it with an AFHDS transmitter; the maker lists the receiver's protocol as AFHDS, so confirm the transmitter uses AFHDS.
- [Radio-controlled pan mount](https://app.soldr.ai/?prompt=I%20want%20to%20build%20a%20radio-controlled%20pan%20mount%20where%20an%20RC%20receiver%20drives%20an%20SG90%20servo%20powered%20by%20four%20rechargeable%20AA%20cells): Four NiMH cells are about 4.8 V nominal, inside the receiver's 4.0 V to 6.5 V range and at the 4.8 V the SG90 maker page lists. The servo's stall current is not documented, so keep the load light. Learning project. The battery holder's two leads go to the plus and minus pins of a spare receiver channel header through jumper wires.
- [Throttle-stick LED dimmer](https://app.soldr.ai/?prompt=I%20want%20to%20build%20a%20throttle-stick%20LED%20dimmer%20with%20an%20RC%20receiver%2C%20an%20Arduino%20Uno%2C%20a%205%20mm%20LED%20and%20a%20resistor): The Uno reads one channel and sets LED brightness with PWM, so no motor or high current is involved. Power the receiver from the Uno's 5 V pin and pick a resistor for the LED's current. The maker page gives no signal voltage level for the receiver output pins; measure it with a multimeter before connecting it to any 3.3 V board. Learning project.

## Common mistakes

- Supply the receiver with 4.0 V to 6.5 V only; a 2S LiPo (about 7.4 V) is above the maker's range ([source](https://www.flysky-cn.com/r6b-canshu)).
- AFHDS receivers bind only to AFHDS transmitters, so check that your transmitter uses the same protocol as the receiver before expecting them to bind ([source](https://www.flysky-cn.com/r6b-canshu)).
- The 500 to 1000 m range is 'in the air'; near the ground or indoors it will be shorter, so range-test before relying on it. The maker page gives no signal voltage level for the receiver output pins; measure it with a multimeter before connecting it to any 3.3 V board. ([source](https://www.flysky-cn.com/r6b-canshu))

## Not covered by the official source

- The maker page lists no receiver current draw, no failsafe behaviour and no pin table.
- Compatibility with a particular transmitter model comes from the product name; the maker page lists only the AFHDS protocol.
- No source states any 2.4 GHz use rules for this receiver, so none are given.
