Voltlog #33 – Ublox 7 GPS USB to UART Conversion Hack

In this video I am hacking this vk-172 cheap usb gps module to use UART instead of USB. The module contains the ublox 7 chipset which is quite nice and it makes it much more useful having an UART interface.

PIO10 > pin 33 controls the hardware pin remapping feature
PIO10 low = UART remapped to PIO15 > pin 36 and PIO16 > pin 37
PIO10 high = UART on standard TX on PIO6 > pin 19 and RX on PIO7 > pin 18
