Finestra miner teardown

[shawaj]

Observations so far.

• Using a Raspberry Pi 4b 4gb
• Seeed wm1302 concentrator
• Appears to be using OpenBalena
• Does not have an exposed Ethernet port (but later versions apparently do)

[shawaj]

Button appears to be between gpio16 and ~ground~ 3v3

[shawaj]

SPI ce0

[shawaj]

Tri colour led / RGB

Chip A3 0mG seems to be LED driver

Input seems to be connected to gpio26, gpio20, gpio07

[shawaj]

SPI seeed concentrator

https://wiki.seeedstudio.com/WM1302_module/

[shawaj]

Still need to work out which is the reset GPIO pin number (forgot) but once we know that addition to hm-pyhelper should be trivial

[shawaj]

Config.txt:

dtoverlay=spi0-1cs,cs0_pin=08
dtparam=i2c_arm=on,audio=on
arm_64bit=1
avoid_warnings=1
disable_splash=1
gpu_mem=16

SPI seems to be on standard pins but instead of using dtparam=spi=on is using dtoverlay=spi0-1cs,cs0_pin=08

reset pin is physical pin 11 / gpio 17

[shawaj]

Added in #103 but need to test the button and LEDs to confirm they're working correctly

[shawaj]

Working as of https://github.com/NebraLtd/helium-miner-software/pull/364 but still need to test that button and LED working correctly

[salmanfarisvp]

LED Status https://thefinestra.com/led/ and https://thefinestra.com/faqs/

[shawaj]

Thanks @salmanfarisvp 👍
