#12 [Layout] TP301: a really large programming trough-hole pad

A programming pad for an old fuel gauge which neo900 uses for n900 compatibility because of bme driver being a proprietary blob.

Size can be reduced.

Also otherwise unusable spaces like holes in sim holders might be used?

Track considerations:

• 21v
• 50 ms pulse length. 1 pulse per byte. 10 bytes.
• 0.5 ms rise and fall times (even with 21v considered a slow edge)

Notes:

• Programming might be needed for correct operation since there will be some unknown offset.

Not really a severe issue. Right now hole goes to the northwest of LOWER in 0f0d6183cd
