The charging problem was also diagnosed with the help of the board scans from @nataliethenerd.com 👀
Turns out one of the fuse detection pins on the PMIC was broken. Fixed that and the GBM charges fine now🥳

working back and forth between the layout editor and the schematic editor, i created this hierarchical schematic view. i like the top-level sheet to look like a block diagram so it is easy to read.

My guess is this GBM had liquid damage. There was a lot of water-soluble brown stains on the inside, prolly Coke. That leg on the PMIC was badly corroded and broke off halfway.
Now I’m considering getting a new battery, since the two originals on hand die very quickly🤔

Update!
1) I found an estimate from 2010 (doi.org/10.1002/pmic...) which is close to mine,
2) a similar calc (www.proteinatlas.org/humanproteom...),
3) someone emailed with their wonderful unpublished paper which has a very accurate answer (again similar but much more rigorous). Watch this space!

How many proteins in the human proteome have transmembrane domains? And of those, how many examples with n TMDs are there?
Couldn't find an answer, so I calculated it from Uniprot data with some #RStats magic (and I did some model organisms while I was at it). 🧪

somewhat related, the week i had to bring up a PMIC at work was the worst week i've ever had in years of embedded work

repebble.com is back! @ericmigi.com and his small team at Core Devices have revived the beloved Pebble smartwatch, Core 2 Duo. What you might not know is that while maintaining the iconic Pebble design, it incorporates #nRF52840 SoC and #nPM1300 PMIC.

'Multiphase buck controller'. I was going to guess it's a pmic. Last time I saw that many passives was a pmic with 8buck converters.

DDR5 RAM Serial Presence Detect chips tell a computer about the RAM specs. It has 1024 bytes of EEPROM storage, temperature monitoring, and pass-through access to a Power Management IC (PMIC). I wrote a very hands on low-level demo on how to access the chip using a Bus Pirate

Soo I’ve been learning about Meshtastic.. and now I’m down that rabbit hole. Which has resulted in the ungodly mess from me frying the PMIC on the expansion board, but now I want to make an ISAC unit from division for it. #3Dprinting #meshtastic #LoRa

al final mi caso es clavado a éste, retiro el PMIC ese y se va el corto, ahora tengo q pedir uno, y reprogramarlo con un analizador lógico, las posibilidades de q ésto funcione las pongo en un 25%
