Further the main UART (serial port) is located on the same pins ( 0 and 1)

The output voltage can be switched between 5V

3DE Premium PLA is a safe choice for a good everyday material

3DE Premium - Conductive Filament - 1.75mm - 1kg Display Further the main UART (serialConductive filament 1kg This conductive filament is a modified PLA which is designed for low current circuits. The material appears more flexible than normal PLA and will be experienced as having a poorer fusion and adhesion to the workpiece plate. The material is available in 1. 75mm. This conductive filament is used as an antistatic material and has good mechanical strength.
