100M Logic Analyzer & Raspberry Pi Development Board

Attention! Attention! Attention!
This project uses a minimum package size of only 0201, requiring extremely high hand stability and coordination. Please consider replicating with caution, as the failure rate may be high!
 
     OK, so...
 
this project is a remake of the open-source Raspberry Pi logic analyzer on GitHub [click ->]. The main controller is a Raspberry Pi RP2040,
with an I2C interface and one ADC interface, and three onboard WS2812E-1313 RGB LEDs. Each I/O port uses fast recovery diodes and resistors for protection. Due to the low speed,
equal-length wiring was not used. Testing showed it can run the firmware normally.
(It's a double-layer board; equal-length wiring would double the size! For a compact and exquisite design, this was omitted.)
 
Oh right, and this is a double-layer board... which means you can get a free JLCPCB matte black immersion gold PCB prototype!
————>>On the order page, select 1.6mm board thickness, matte black solder mask, and 1u immersion gold coating. Then select to use 2-4 layers of immersion gold coil for free prototyping.
 
Next, here are the pictures!

view. A video demonstrating the RGB lighting, along with my own code for testing RGB LEDs, are attached. Feel free to download them if needed!
For running the test code, I used thonny!
