Main Controller parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.
#PartQtyWhat it does
1 ARM Microcontroller 1× Low-power ARM MCU (e.g., STM32, nRF) running activity algorithm, 8-12 mA average draw.
2 Radio Modem 1× LoRaWAN or Bluetooth Low Energy (BLE) modem, 868-915 MHz ISM band, 20-100 mW transmit power.
3 Collar PCB 1× Custom flex or rigid PCB integrating MCU, radio, sensor ports, and battery charging.
4 SMD Passive (R/C/L) 1× Surface-mount resistors, capacitors, and inductors, typically in 0402 to 1206 packages, that set voltages, filter noise, and time signals on a circuit board.
5 Connector 1× Mating plug-and-socket pair that joins two lengths of wiring or a cable to a board so a circuit can be assembled, serviced, and separated without soldering.
