Arduino based Serial Transmitter
Commercially available transmitter and receiver pairs are usually PPM or PWM based. Using them with any microcontroller is problematic as you require a lot of pins and hence isn't that efficient. Using Serial modules like Xbee or HC-05 can solve this issue but will have less range as compared to the commercial PWM/PPM RF pairs, hence cant be used for applications like drones or UAV. To solve this, we can use NRF24l01+ (PA+LNA) module which theoretically provides a huge range of 1100m (700m+ in ideal conditions) along with Arduino to make a versatile commercial Like Transmitter which can be configured to send almost everything! This design was made considering these problems.
This project was also featured in Altium Stories.
Features of the design:
- Arduino Pro mini based
- NRF24l01 + PA +LNA as RF
- 2 Joysticks (4 analog inputs)
- 12 Digital buttons
- 2 buttons for Menu settings
- OLED for user interface
- 2 74LS151 Multiplexers
- HC-05 Compatible
- 2 Toggle Switches
- Powered by any 2S lipo/li-ion battery pack
