A kit to make a parallel real time clock for the RC2014.
It started with the MG001 four digit seven segment display. This could obviously be used as a clock display when the RC2014 is not being used for anything else, provided it had a Real Time Clock (RTC). I couldn't find an RTC out there that fitted my needs (amongst other things, being easily accessible over a standard RC2014 parallel bus), so I designed this.
The MG002 can be used to maintain and output time, date and/or numeric day of week. A lithium backup battery (not supplied) keeps the clock running when power is removed. When combined with a display such as the MG001, and a host RC2014, it can be used to provide a fairly* accurate clock and/or calendar.
A PCB and all components required (EXCEPT the CR2032 Lithium backup battery) are included, including sockets for all ICs. A PDF with full instructions is available at the link below.
MG002 has been designed for RC2014 with reference to the RC2014 Module Template. All pinouts used and the physical outline are in compliance with the RC2014 Module Template.
RC2014 is a trademark of RFC2795 Ltd.
MG002 has been designed for hobbyist use only and is not to be used for safety or business critical applications. The kit assumes basic through-hole soldering skills.
*fairly = about the accuracy you would get from the clock on your microwave
