Data Sheet

This servo driver board for the BBC micro:bit allows up to 16 Remote Control
(RC) servos to be driven simultaneously. It is based on the PCA9865 driver IC.
The board includes an integrated Edge Connector for the BBC micro:bit.
Expansion Pads allow the connection of this board with other compatible
micro:bit accessory boards using the “Link” pluggable pin header
(www.kitronik.co.uk/4162)
The board produces a regulated supply that is fed into the 80 way connector to
power the inserted BBC micro:bit, removing the need to power the BBC
micro:bit directly.
Power (maximum 5.5V) can be supplied to the board via either the dedicated
screw connections, or the 0.1” pitch Power connector, for instance from a
standard receiver battery pack.

Inserting a BBC micro:bit: To use
the servo driver board the BBC
micro:bit should be inserted firmly
into the connector as shown left.
The board has been designed so
that the BBC micro:bit can be
inserted either way around (facing
forward or backwards).
Note: ‘Link’ functionality is only
enabled when facing the link
interconnect header.
