Someone wanted to see the guts of the insteon hub, so here it is. I researched the main smd components and found these parts on the Insteon hub, date printed on pcb 20170613 -
Major components on the Insteon hub pcb -
PIC32MX695F512H microcontroller
PIC18F25J10 microcontroller
PIC16F688 14-Pin Flash-Based, 8-Bit CMOS Microcontroller with nanoWatt Technology
PIC25LC256 2.5V SPI Serial EEPROM
PICSST25VF016B SPI Serial Flash (3 pieces)
Si4421 Universal ISM Band FSK Transceiver, power output +7 dBm (5 mW) The Si4421 FSK transceiver is designed to cover the unlicensed frequency bands at 433, 868 and 915 MHz
SMSC8720a Small Footprint RMII 10/100 Ethernet Transceiver
Crystals - 25, 10, 8, and 5.529 MHz (5.5296 MHz allows integer division to common baud rates)
Five empty headers J2, J4, J8 (RF ICP), J15 (PLM ICP), J19 (PIC32 ICP)
The unit does not obtain power from an external DC power supply, it is connected directly to AC mains and has it's own internal PS.
