More coming in a week or so. I'll assemble some this weekend.

I am so cramped for space on this thing there is no chance to fit on any isolation... I don't think it would entirely mitigate the risk to the PC of hot plugging the 0.1" headers. The solution is to use a connector designed for hot plugging - but I don't see how to physically fit one! I could s...

Right so I've hit a brick wall with these things. The problem is that with headers you can't stop a user connecting the USB at the header end (rather than the USB plug) if they are using a non-earth referenced computer and the module is installed in an earth referenced device (e.g. retro computer). ...

Fonzie got the last of this batch. They went quick.

I will order some more parts tomorrow to build up my remaining blank PCBs. They could well be the last ones I make probably until I've got PCB assembly & testing sorted.

I made another batch so I have some more stock now.

I think my impression was that A17-A19 are "broken" through the cpld when in 27C200 mode. But i guess thats not the case. No I don't have enough pins to do that. The STM 32, pads (A18, A19) and pin 1/A17 pad (A17) are wire ORed on the 5v side of the buffers. I thought about putting solder...

The module might be in "no wire rom switch" mode and when the USB powers it and the H4 is off it sees that as a long reset press (>3s) - which always goes to ROM 0. In the options menu check... a) reset wire free ROM switch is N (disabled) b) ROM switch pull up is Y (enabled) Then C to com...

Ahh... it is software not a piece of hardware.

The PLCC to DIP adapters arrived today so I can finally try my project with a 68HC000 I have had for months.. Photo0962b.jpg Obligatory sysinfo shot: Photo0964b.jpg This is running at 36MHz. The fast RAM isn't as fast as it could be because I have a noddy refresh in place at the moment - do a refres...

@cmorley I have to order the program adaptor to upgrade the boards but plan on upgrading. I don't understand this - do you mean update the firmware? If so you don't need any special hardware just the USB connection & a DFU utility for your platform of choice (I use the STM Cube Programmer which...
