Canokey STM32 A+C Edition
Canokey STM32 version implements USB A+C dual interface
Canokey is an open-source hardware keying device that supports FIDO2, OATH, OpenPGP, PIV, and other functionalities. It achieves an experience almost identical to Yubikey at a lower cost, significantly enhancing the security of digital assets.
This project is based on the Canokey STM32 nano version and implements a USB A+C dual-interface design.
Official website: https://canokeys.org/
Hardware reference: canokeys/canokey-hardware (github.com)
Firmware reference: canokeys/canokey-stm32: An open-source USB security token powered by STM32 (github.com)
Note: This project is only for low-cost experience with Canokey, or for learning, testing, and research. The STM32 version of Canokey offers no security whatsoever; the private key can be exported. Do not use it in a production environment!
A secure version of Canokey can be obtained here:
After attaching the original Canokey Pigeon, you can apply a layer of AB glue and then shape it as desired.

Makita 5-cell battery pack with 60W USB fast charging, supports same-port charging and discharging.
Makita 5-cell battery pack with 60W USB fast charging, supports same-port charging and discharging.
Important Notes on the Solution
: 1. The IP2366 is a 140W charging chip. However, this 140W means it supports a maximum of 140W fast charging protocols. The specific charging power will be determined by the materials and layout of the external step-up/step-down MOSFETs and inductors. Different power ratings result in different circuit costs.
2. The MOSFETs used with the IP2366 cannot be easily replaced. This solution uses a maximum charging power of 60W, and it can only stably pass high-temperature testing with a heatsink. Therefore, applications without a heatsink will be limited to 45W to avoid product risks. The mature implementation of a MOSFET requires careful temperature testing and load testing on a small batch of boards before it can be judged, resulting in a long testing cycle.

Southwest Jiaotong University NFC Campus Card
The PCB is drawn based on a map of Southwest Jiaotong University's Xipu campus. It only requires soldering the IC card and two LEDs to function properly. Please remember to update your student ID numbers.
It's not technically sophisticated, but it looks really cool.
