Many thanks Phil, I am just glad that it was my fault and not a "failure" as such because that would shake my faith in Orange modules! 'Pity though but fortunately HK still have them in stock. Will your 2+1 Digispark still be OK or will that be fuggered too? The battery was only "storage charged" to start with so that would be why it went so completely flat overnight...... and yes, it had an aerial!Phil_G wrote: ↑18 Dec 2019, 13:01 Its possible that leaving it on killed the module Paul. The PA may have simply overheated. Or, heres a thought, while the battery is up everything is hunky dory but as it slowly discharges, a relatively big battery with a light load will be in the brownout region for a prolonged period of time, during which unpredictable stuff happens - generally switching becomes linear and therefore dissipates a lot more heat, things stop oscillating and a PA can draw large DC currents, the processor will become erratic and might lock the PA on permanently (normally MU is 10% or less). A brief brownout is harmless but yours would have been held there for hours, its just an opinion but I expect thats why. I've accidentally left trannies switched on overnight but never had one drain the battery fully.
Or, maybe the PA just got hotter & hotter with being left on for hours inside a sealed enclosure. I dont know how OrangeRx spec their boards but I would have thought continuous operation would be ok.
Since its a 'recent conversion' so presumably a new/unused module, it could simply be ELF, it happens, thankfully very rarely, but it happens...

PS presumably it had an aerial?
