RTC module
Parts List:
RTC
RTC
SV3
CONN_RTC
The RTC module is a traditional Real Time Clock module. Unfortunately we are no longer
permitted to post the battery with the kit, so you will have to get your own. The battery you
need to get is a CR2032, or a LIR20132 (rechargeable).
You can mount the RTC module directly on the board, or as a separate board connected by
flying leads.
The markings on the board need to match up with the markings on the module. In particular,
the VCC and GND need to be in the right orientation.
The WiFi module has it's own instruction manual. Please refer to that if you have the WiFi
option.

The RTC module has two sets of contacts on it. You can use either the side with the pins
on it or wire up the other side with flying wires. If you use the side with pins, you should
carefully remove the two unused pins (see hint). If you use the contacts on the module,
you should leave CONN_RTC off the board.
•
If you receive the connector header as a single strip, break off 4 pins for SV3.
Hint:
Trimming the extra pins on the RTC module
ONLY if you want to mount the RTC
module directly onto the main board
(you can also do it via flying leads),
trim off the pins “32K” and “SQW”
using a pair of precision side cutters.
If you want to mount using flying
leads, you can skip this step and use
the four holes on the other side of
the board.
