preci-dip
I have trouble finding a good keyword name for this thing that seems vaguely matching various following names:
- preci-dip sockets & pins?
- machined goldpin/pin/dip sockets & pins?
- mill-max dip sockets & pins?
A TME search that seems to give relevant results.
They seem to have lower profile than generic square-shaped sockets+goldpins, as exemplified in corne keyboard builds where a LiPo battery seems to fit inbetween. But I can’t find more details, and also (how) do pins (male headers) look/work/differ on those.
fanless, USBC-powered MiniPC
fun with low-power displays
- “Nokia 5110 LCD” 84x48 px, b&w, 3.3V
- "Sharp memory LCDs"
(specs overview;
digikey search,
filter by Sharp)
- the first number in their name seems to indicate size (diagonal?) in inches - e.g.: “LS027…” -> 2.7"
- the connection seems to be “SPI over (10-pin? 0.5mm?) FPC” (or “…FFC”) where FPC seems to mean “flexible printed circuit” and FFC to mean “flexible flat cable”. The FPC/FFC seems to be standardized, with 0.5mm pitch connectors and breakout boards existing for various pin-widths and easily available.
- LS010B7DH04
- LS011B7DH03 - 1.08" ~32x14mm outline, 160x68px; used in the popular “nice!view” display module;
- LS012B7DD01
- LS012B7DD06A (rgb, round) / LS012B7DD06 (?) / LS012B7DH06A (?) - 1.19" 240x240px; (datasheet) needs 5V :(
- LS013B7DH05 - 1.26" ~30x25mm outline, 168x144px; (datasheet) seems 3.3V based
- LS013B7DH03 - 1.28" ~31x27mm outline, 128x128px;
- LS013B7DD02 (rgb, round) - 1.29" ~37x36mm outline, 260x260px; (datasheet) needs 5V :(
- LS013B7DH06 (rgb) - 1.33" ~32x27mm outline ~24x24mm active, 128x128px; (datasheet) needs 5V :(
- LS014B7DD01 (rgb, round??) - 1.39" ~39x38mm outline, 280x280px;
- LS018B7DH02 - 1.8" ~42x31mm outline, 303x230px;
- LS021B7DD02 (rgb) - 2.13" 320x240px; (datasheet) needs 5V :(
- LS027B7DH01 / LS027B7DH01A - 2.7" ~63x43mm (outline) 400x240px; from datasheet it seems they need 5V (so an extra boost converter from 3.3v) :( Reportedly, the “…A” suffix should indicate up to 2 bad pixels per display, whereas non-A should indicate zero (or untested?).
- WeAct Studio ePaper (github)
- 1.54" ~50x33mm module outline, 27x27mm active area, 200x200px, seems 3.3V; (datasheet) I think it supports partial refresh? not sure yet what is the power consumption
