Internal Components Overview
Main Circuit Board
The main printed circuit board (PCB) contains several key components:
- Microcontroller: Labeled as U2, with the designation SIC21434.
- Other Integrated Circuits: U3 and other smaller ICs are present.
- Passive Components: Resistors (R1-R9) and capacitors (C5-C6, C10-C13, C15-C16, C18-C19, C21-C22) are visible.
- Diodes: D2, D3, D4 are identified.
- Crystal Oscillator: Labeled Y1.
- Connectors and Test Points: Includes P1 (likely for display or programming), PT36, PT37, US, VDD, UPP, GND.
- Power Terminals: Labeled B+ (positive battery), GND (ground), and BAT (battery connection).
- Communication Interfaces: Pins for SCL (Serial Clock), SDA (Serial Data), CSN (Chip Select Not), NRST (Not Reset), and DAT are present, suggesting an SPI or I2C communication protocol.
- Antenna Connection: A dedicated point labeled ANT indicates wireless communication capabilities.
- Indicator Markings: Markings such as "B/R 白黒" are present, possibly indicating connection types or status indicators (白 means white, 黒 means black in Chinese).
LED Display Board
A separate PCB features an array of LEDs, labeled LED1 through LED28. These LEDs are likely used for displaying weight measurements and other information on the scale.
A power connector labeled PW1 and power terminals B+ are also visible on this board.
