R9M Inverter Mod
- To benefit from the higher bitrate of 400 kilobit per second using
OpenTXyou need to add a pullup resistor to the inverter of the serial port on the R9M 2018🗻🆙
- Strongly suggested to be done for anybody looking for higher than standard packet rates using
⚠️ This is only required for the 2018 version of the module which has a
ACCST logo on the case 🔍
Easy - connect a 300Ω to 1000Ω resistor between the
3.3V and inverter pin as shown on the picture 👧
X9Donly does 400 kbit/s and does not allow lowering the bitrate to 115200 bit/s - 400k Mod is not required.
X10S Express400k Mod is not required.
X10Smodification is required 🙅
X12modification is required 🙅
QX7allows configuration of the bitrate in the OpenTX hardware menu. ELRS will work fine using 115200 bit/s but the modification is required for 400 kbit/s 🙅♀️
