This is the Toast-R-Reflow controller “backpack.” It mounts on the back of a 80x36mm 2x16 LCD display.
This variant uses an ATMega328P controller and a MAX31855 thermocouple amplifier. It’s more expensive than the model I controller, but there’s lots of room for more features in the flash, it has connections for 3 buttons instead of just 1 and an FTDI serial port. Also, the MAX31855 has a much wider temperature range while having higher resolution.
