I needed a clock module students could use on their BBs. I tried a few designs and came up with this right angle concept. I am sure it has been used by others.
The PCB is in two parts. The battery, clock chip and associated parts are on the main board. The I2C pullup resistors are on the upright PCB. More importantly the upright board provides a nice way to label the I2C and power signals.
The header pins come through the main PCB and soldered surface mount style to the upright.
The PCB did not come out well but it works, It was an experiment.
