Prototyping with the RCxxxxHP-DB
All pins to the module are available though standard pin rows using a pitch distance of 100 mil
(2.54 mm). This simplifies the build of a standalone application just by making a small plug-in-
board to the existing Development Board. Battery connectors on the bottom side are available
for self powered demos, and REGOUT is available on P13. The Battery clips and most of the
connectors are not mounted from factory, but part numbers are available from the Bill of
Materials at the end of this document. The idea is that an external MCU and application
specific sensors etc easily can be connected to the Development Board as a proof of concept
for the final product.
