Changing the circuit to be powered from v_lipo with the gpio hooked to shdn*
and controlling a FET switch on the output might be smarter someday?

+ 6-pin micromatch with locking ears
+ 2 * 9-pin screw terminal strips
+ 5x1 100mil straight header

+- the LCD digits we've used, Lumex LCD-S101D14TR, are only available now if
+ we're willing to order 3150 pieces at !.85 each or $5,827.50. That's just
+ not reasonable when we only need 3 per unit and a big build might be 35
+ units!

+- DK and Mouser both have the Varitronix VI-611-DP-FH-W in stock. This is a
+ 6-digit LCD display whose digits are 25.4 mm tall instead of 34.54. This
+ LCD module would require the PCB width to grow an inch in width to 5.5
+ inches. A quick look at the FreeCAD file suggest this is manageable without
+ a complete re-design of the panel. By using the panel to only expose 3 of
+ the digits, we could mimic the existing functionality. At $16.27 for q5
+ and above from Mouser, this seems like a credible way of making more TeleLCO
+ in 2023?

+- we should have 31 SOC left after TeleMega v6.0 build if all goes well, which
+ means we should target a batch size of 30 boards.

+- 1170NF in orange is hard to get. The part number is 1170-001-150.
+ mteagleent.com seem willing to sell me 30 pieces for $1,520.40 plus $15.00
+ shipping. Pounce on it?
