Using the Grove Serial connector

The Badge Team thoughtfully chose to include a couple of Seeed Studio Grove system connectors to the 2018 badge. Looking at the rear of the badge, they are either side of the unpopulated 3.5mm jack footprint, top right.

  • On the left is the Grove I2C connector \<anyone using this?>
  • On the right is the Grove UART connector

The Grove UART is helpfully labelled "UART4". To use it in Python, it is actually number 2!!!

Example:

import machine
u = machine.UART(2, 9600)
g = u.readline()
etc...

can be used to communicate with the Seeed Studio GPS module. Seeed Studio
