Kogan SmarterHome Smart Power Board With USB Ports & Energy Meter

Kogan SmarterHome™ Smart Power Board With USB Ports & Energy Meter - (KASPS30WACB) - Manual

Programming Notes

Warning This board is mains powered. Do not do ANYTHING while the board is powered. Power the board via the 3.3v and GND pin and do not connect the board to the mains until you are fully disconnected and the board is fully reassembled.

To program the board you will need to disassemble the powerboard and solder jumper cables to the CEN, TX, RX, 3.3v and GND pins. You will also need to bridge the CSN pin on the back of the module to GND (e.g back of the chip) to put the board into programming mode.

Attach 3.3v, GND, TX and RX to your serial adapter and tap CEN to GND while attempting to flash the board in ltchiptool. It may take a couple attempts to get the timing right, but you should see the board flash and then disconnect the CSN-GND bridge after flashing is complete.

GPIO Pinout

Pin	Function
P9 (TX1)	BL0942 UART TX
P10 (RX1)	BL0942 UART RX
P6 (PWM0)	Port 1 relay
P7 (PWM1)	Port 2 relay
P26(PWM2)	Port 3 relay
P24(PWM4)	Push button
P8 (PWM5)	Status LED (inverted)

Note: The button and LED are not configured to do anything in this configuration, but they are included for completeness.
