Hezhou CC watch backplate

Overview

Hezhou CC Meter Simple Expansion Baseboard

Update:
June 16, 2024: V3 Update. 1. Added CH22K PD decoy circuit; DIP switch configurable input voltage. 2. Replaced push-button switch with toggle switch; fixed poor switch contact; increased current carrying capacity (V2 casing compatible with V3).

December 12, 2023: V2 Update; added input reverse connection protection circuit.

Self-use baseboard; simple function, used for device debugging and monitoring start-up current.

Design principle is simplicity and low cost, so not many functional circuits were added.

Three switches control input/output and the CC meter's power supply respectively.

The casing is magnetic, easy to disassemble and adjust functions by pressing buttons.

When the input is greater than 5V, the USB output is also greater than 5V. Pay attention to the input voltage when using USB

(casing file attached).

Remember: “Your class is the noisiest”?
I just went to travel around, and a netizen talked about it - I remembered what the head teacher said: Your class is the noisiest. It's so familiar. Hahaha, how many netizens' classes have received th
Can the interrupt flag of the CAN chip be reset by itself?
MCP2515 is a CAN bus chip. When receiving a message, if the CANINTE receive bit is enabled, the CANINTF receive bit is set to 1 and an interrupt is generated. Theoretically, after the MCU detects the
