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