A replica of the LCSC ESP32S3R8N8 development board!
Demo video: https://www.bilibili.com/video/BV122yYYdEci/
Source code is attached. Developed using VS Code + PlatformIO based on Arduino! Low-power design: opening the toggle switch wakes up the ESP32 via an IO interrupt; after closing the box, the entire system enters DeepSleep mode. The front and back patterns
of the replicated LCSC ESP32S3R8N16 development board
are now complete .

Bluetooth speaker network radio
LCSC development board ESP32R8N8, SI4732
The radio supports FM, AM, and SSB, and the reception is currently quite good.
The front cover hole cutting failed; a 3D-printed front cover has been completed but hasn't arrived yet.
The screen display is incomplete and is still being modified.
It uses a LCSC development board with
an ESP32R8N8
, an ME6217C33M5G power supply, and
an SI4732 peripheral circuit.
For the
screen and headphone amplifier circuits,
if the headphone jack is not soldered, please short
the encoder and telescopic antenna
. Points of deficiency are welcome. Guidance is warmly welcomed.
The design project referenced the LCSC Open Source Plaza.

PCB rulers from Guangdong University of Technology (free of charge)
I received the JLCPCB gold foil voucher, which expires today, and I'm wondering what to do with it. I remembered the PCB ruler I made before, but I'm too inexperienced, so I had to hand-draw it. Sorry! The PCB is now complete, and the result is good! (This is the previous description.) If you think the drawing is ugly, you can copy the front side to the back side.
Damn, after finishing, I realized the units weren't consistent. I kept using mm for drawing lines, which confused me (lol).
Here's a screenshot:
This is a free ruler; I'll modify it if needed. I mainly wanted to practice my skills.

UGREEN 300W Fast Charging Power Supply Board
The UGREEN 300W boost power supply board uses the EG1164 chip, supports 12-24V input, has an XT60 interface, and comes with a switch.
Video Link:
Bilibili Video -- Function Demonstration and Introduction
Project Introduction
I bought a UGREEN 300W fast charging protocol board for 48 yuan on Xianyu. Since the board requires 29V input, I used the EG1164 to build this board, which supports 12V and 24V input. It works normally after testing.
Project Function
A boost converter board to power the UGREEN 300W fast charging protocol board.
Project Parameters
XT60 Interface Input
Supports 12V-24V Input
With 12V input, 210W output Under load, the highest MOSFET temperature reached 73°C
. With 24V input, the LDO temperature is higher at 56°C, so a fan cooling is not necessary .
Precautions
The power indicator light needs to be soldered after the protocol board is soldered. Do not touch the EG1164 chip during normal operation!!! Touching it will burn the MOSFET
Assembly Process
The released version has added a fan mounting hole, modified the rear opening position, and added a fan interface to the board.

[PCB Design] JOKER Playing Cards
This is a card I designed myself; feel free to use it if you like.
The cover is PCB4! It's been verified and is perfect.
This is a top-tier PCB printing board. I did the PCB editing, and the pattern design was done by @ironwings.
