This is an RF ESP32-S3-based 10-channel Transmitter and Receiver which can also be used with the ESP-NOW protocol.
PARTS
- ESP32-S3 WROOM-1U
- NRF24L01+ Transceiver Module
- SSD1309 2.42 inch OLED
- 2 Joysticks
- 4 Switches
- 2 Potentiometers
PLAN
This is an RF transmitter with 10 channels, all of which support PWM output. The 10 channels include: 4 from joysticks 2 from potentiometers 4 from toggle switches
The setup includes a 2.42-inch OLED display to show the status of each channel, bind status, and battery level.
The receiver and transmitter will be programmed using an FTDI module.
The transmitter is designed to run for 5–6 hours on a 1000mAh LiPo battery (ideally).
The code is subject to change depending on in hand testing currently its just a sample code for controlling 10 servo motor with the 10 inputs.

Questions
How big is the ESP32S3 Transmitter PCB?
It measures 30.2 × 40 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ESP32S3 Transmitter use?
39 parts, built around the ESP32-S3-WROOM-1U-N4 and MIC5219-3.3YM5. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the ESP32S3 Transmitter KiCad files?
From the ANSHUMANDOCX/Transmitter_Receiver-Using-ESP32S3 repository on GitHub, at the commit this page was made from: the board is Transmitter/ESP32S3_Transmitter.kicad_pcb and its schematic Receiver/ESP32S3 Receiver.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ESP32S3 Transmitter design in my own project?
Its repository states no licence, so its author keeps all rights: ask ANSHUMANDOCX before reusing the design.
