AffoFly_RX

AffoFly RC Receiver. It is a part of AffoFly -- a complete guild of DIY drone at affordable cost. It is developed to only work with AffoFly_TX currently but might work with more protocols in the future.

Features

• Popular 2.4G frequency which is free to use in most countries.
• Binding procedure does not require computer.
• 12 channels on CPPM/PPM output
• 6 channels on PWM output
• LED status indication

Required Materials

I've estimated total cost of the whole lot should be something $3 - $4.

| Material | QTY | | -------- | --- | ---- | | Arduino Pro Mini 3.3v | 1 | | NRF24L01+ | 1 | | LED RED | 1 | | LED BLUE | 1 | | 2.54mm PIN | n | | Jumper Socket | 1 | | 10uF Electrolytic Capacitor | 1 | | 0.1uf Ceremic Capacitor | 1 | | 3.5mm Audio Jack | 1 (optional) |

Warning

This software is a work in progress and has not been tested in field yet. Code should be only used for reference until I feel comfortable to make it as a release version. DRONE CAN BE VERY DANGEROUS SO REMOVE YOUR PROPELLER UNTIL ACTUAL FLY!!!

Side Notes

• Radio Frequency. The NRF24L01+ module provides 126 channels (0 - 125) which map to frequencies from 2400mhz to 2525mhz respectively, if you are planning to use it in areas close to residential like even indoor (a lot of WIFI) better stick to channels from 85 (2485mhz) and above to minimize interference, it gives you 40 channels to choose from, for simplicity I prefer starts from 100 and 25 channels is plenty for me. According to List of WLAN channels most WIFI routers are using frenquency under 2484mhz.
