I will be playing with the RTC of the LPC2103 today. Well i should say LPC201x since the LPC2101, LPC2102 and LPC2103 are all the same besides RAM and Flash differences. They all have the same PIN-OUT and HARDWARE.
So yeah im making a Battery addon to my board Here are some pictures. You cant even notice the battery 😀
Ill be sure to add this to the new Rev i make. Also make a 2pin battery port separate from the rest of the pins.
