Hardware Requirements
A free USB port is required to update HardWaves devices.
Surfer
No additional hardware is required to update Surfer, since it connects directly on USB.
One - HW1
A USB-to-TTL UART cable is required.
A FTDI cable like TTL-232RG-VSW3V3-WE can be used, but requires a patch.
Using a sharp cutter, a part of plastic case has been removed, and brown wire has been moved on the pad shown in the image, between orange and green wires.
Any case, UART used signals are: RXD, TXD, RTS, DTR, GND and Power.
WARNING!!! A voltage of +3.3 [VDC] is required.
Signals direction is indicated from the point of view of HW1 board.
