Hope fully this SD breakout will arrive in time and I can wire it up to the Pico.
I put my meter on the USB from my PC to the espruin and it's pulling a steady 110mA while blipping the LED and logging to the serial. I think I'll order a 3000mAh battery I've seen for a couple of quid more than the 1300mAH one that would have nicely fit in the case. Just for some peace of mind.
With some work on power management I bet this could get really efficient.
