Seeeduino Xiao Expansion Board - extension board for Xiao main module

A board extending the functionality ofSeeeduino Xiaomodule. Enables faster and simpler prototyping with this miniature main module. On the board there are, among others,Grove systemconnectors,0.96"OLED display,2.0 mm JSTconnector enabling connection ofLi-pol battery,RTCclock, space for lozenge battery andmicroSD card slot. The set consisting of extension board and main module can be programmed using Python language. All the connectors on the board have already been removed and there is no need for additional soldering. The total dimensions of the expansion board are58 x 42.5 mm.

A richly equipped extension board for Seeeduino Xiao.

Slots for microSD card and CR1220 battery are on the back of the board.
