Topic: BM1378 Datasheets (Read 62 times)
Bitmain stopped releasing datasheets with the BM1385. Any information from BM1387 on has been collected from repair materials and reverse engineering.
Okay I have conversed with the 'gpt' and it has come up with some better definitions of the pins that are required for the BM1387 chip.
Here is the conversation so far:

Hope this helps a lot of people out, cause it sure does for me

Hi community,
I am currently trying to develop a very cheap and very efficient BTC ASIC miner with a Bitmain BM1387 ASIC chip and an ESP32-S3 (WiFi + BT) at it's core.
At the moment I am developing a prototype of the mining board, but in order to do that I need to be able to understand what each pin on the BM1387 chip does. So I can connect it to the ESP32-S3 board for controlling and data, such as hashrate, temp. etc.
I have tried using "ABC123 filetype:pdf" on google, no results that I was looking for. I have also tried using alldatasheet.com, no results there either.
I have also also tried looking at the Bitaxe schematics, but I cannot make anything of it as they use a completely different Bitmain chip.
I found the wiring diagram of the BM1387 for use on an Antminer S9 miner (the same miner that uses the BM1387 chip), but this leads me no where closer to understanding what each pin does.
On the PDF that I found the wiring diagram on, there is a 'pin function table' which gives a basic description of each pin, but once again, these 'descriptions' don't give me enough information on what the pin does, what kind of input it takes, if the pin is PWM or Digital or even Analog?, is the pin pulled down/up? (some descriptions state whether or not it is)
These are the kind of questions I need answered, if anyone has any suggestions for what I could do. Better yet, if you have a datasheet of the BM1387, could I please be sent a copy through email?
Thank you, PackedAPunch77
