I placed a backorder today for some more BeMIcroCV-A9 boards since they are not actually discontinued, simply not in stock and still available with lead times. They are saying 17-18 weeks which means I will have my order by the end of October which will come soon enough.
At present I am prototyping a controller board with the CV-A9 plugged into underneath. This all fits into a standard case with a clear lid and is quite suitable and designed for deploying in the field. In my case they will be preproduction units in limited quantities but I am making the controller/motherboard general-purpose enough plus it will have a footprint for the real P2 chip when it's available. So I started with a matrix board proto to give me an immediate start and from this I can finalize the configuration of the motherboard. In the meantime I have posted some information in my Tachyon P2 thread and dropbox as I put this together.
Using a CV-A9 as a CPU module for a motherboard makes the motherboard a lot more general-purpose as you can make up your own custom plug-in modules and add them to the motherboard. The final PCB will also use the 80-pin edge connector with DACs for the VGA although I can use VGA at present using I/O and resistors.
Basic configuration of the actual motherboard itself.
- 2 x SD cards
- IoT5500 module (WIZnet W500)
- 3 x plug-in user modules
- ESP8266MOD with int+ext ant
- Serial Bluetooth
- DS3231 RTC
- QSPI Flash
- 128kB EEPROM (why not)
- USB A
- 3.5mm stereo
- VGA (needs DAC board but can do 8 color mode as is)
- Switcher supply 24VDC in
D.P. has indicated he will take at least 2 CV-A9s plus motherboards. Please let me know in this thread or pm if you need as I can add to my order as well.
