[PRE-ORDER] RTC + Clock Generator Combo Board

This is a pre-order! The expected ship date is sometime in late April to early May. The fab has shipped the assembled boards and they are currently in transit and awaiting customs clearance.

Do you have a previous hardware version or an older revision of HW5 without RTC support but wish you could get it? The StarshadeRETRO RTC+CLKgen add-on module is what you need! This board can add an RTC to any OSCR hardware version or revision with the Adafruit-style Clock Generator. This board could also be used in other projects unrelated to the OSCR.

Features

• Add RTC to any OSCR with the clock generator header. Can be used for other projects as well.
• Drop-in installation when pre-soldered headers are selected -- no soldering required!
• Uses a CR16xx (the same used by HW5) battery, which is located on the back of the PCB. 
• Gives advanced users options:
  • The on-board 3.3V 1000mA (1A) linear regulator can be utilized to provide 3.3V to the main PCB allowing for an easy "headless" (serial-only) HW5 build or the use of an LCD module without a 3.3V out option.
  • Optional support to hardwire VBUS (+5V USB) to the module. This allows the RTC to remain powered by VBUS and not drain the battery when leaving the OSCR plugged in but powered off.
• Purple 4-layer PCB with EING (gold) finish.
• The PCB is made in China. Headers, if selected, are assembled in the USA. All other components were assembled in China.

Compatibility: Verified compatible with HW5 and HW3-ALTER (SaveTheHero) -- should work on any OSCR that has the ClockGen header and can physically fit it.
