It saves a little money on the development board; it's ready to use right out of the box, making it very user-friendly for program burning and testing.
The antenna PCB has been removed for easier disassembly without affecting the signal.
The following colored PCB images are from the second version. If you don't want to prototype the colored PCB, just delete the images and icons in the project.

A 6-digit LED display module designed based on the sensor interface of the Newland M3 development board.
It has three status interfaces, one data interface, and is powered by a 5V power supply. There is slight leakage current after power is off.
Driver section:
The first 8 bits of input data control the segment selection of the digital tube, and the next 8 bits control the digit selection.
Example usage:
Actual display:
The leftmost digit is the first digit.

Wireless charging IP6808 compatible with Apple devices - detailed specifications
Based on a circuit designed by an expert, I made some modifications.
It uses an IP6808 as the main controller, requiring minimal external circuitry. The maximum power is 15W.
I made some changes, including adding a few extra wires, for improved stability. For details
on printing custom icons on the JLCPCB panel,
please see the demo video.

HoloCubic Reissue [with Complete Sharing Tutorial]
Replicating the Holocubic project
The problem requires
replicating Holocubic. The project mainly consists of two boards (main board and screen board). There are two versions of the main board, v1 and v2, both with modifications compared to the original. Version v2 is the closest to the original. For easier PCB routing, only the package of the main control chip was modified. Version v1 (four-layer board): Added a battery module and a power switch. Version v2 (two-layer board, recommended): Modified the ESP32-PICO-D4 package. Software instructions, 3D shell files, etc., have been uploaded. Software open-source address: https://github.com/wan-h/holocubic_reproduce.
