Description

Shield for Wemos D1 Mini. It provides two 3.3V GPIO and two 5V GPIO each with supply voltage, and ground terminals. The two 3.3V GPIO have provisions for optional pullup resistors. These can be used with sensors or 1-wire devices requiring pullup. Two additional GPIO are for 5V devices with level shifters to provide 5V Input or Output. I designed a 3d printable bracket to hold this board and attached the stl file.
