### Remote Control Part
* **Before Modification**

![1e25b8acc55335a909d1ce3824a509e.jpg] **The appearance of this remote control is basically unchanged, mainly the internal motherboard has been replaced, and the original place where the phone was clamped has been changed to an ink screen. At present, this ink screen can only display channel values, and no other functions are used, so the menu has not been written yet. **

![f9f992988389ad3526f7e0f3f1a49af.jpg] **The charging port has been replaced with an extremely advanced type C port. **

`This remote control can only be said to be usable at present, and I have not tested its specific performance. I am not a model airplane player and I am not familiar with the relevant protocols, so the code is not perfect enough. Interested students can further improve it.

` ### Receiving part
* **The wireless module selected is the commonly used 2.4G module nRF24L01, which provides 6-way PWM interface and serial port. **

## Device selection

* The main control chip of the remote control end is STM32F103C8T6, which uses 7-channel ADC, 6 of which are rocker potentiometers and 1 measures battery voltage. Two SPIs are connected to the 2.4G module and the ink screen respectively. Add a few buttons and LEDs, and the IO is basically enough.

![微信快照_20230209163637.png] * The charging chip is `IP5306_CK`, which integrates a boost converter, lithium battery charging management, and battery power indication multi-function power management. It was used by power banks before. This remote control of Xiaomi just has a power button and four power indicator LEDs, which is very suitable.

* The nRF24L01 module can choose the module of `泽耀科技` or `亿比特`, and these two modules can be replaced with each other.
