v2.3 Changes

Done

• Remove the BI connection to the ESP32 and pull low.
• Remove the ESP32 to BM1397 CLK connection and level shifter
• Add a ESP32 USB JTAG connection and USB port
• Add BOOT and RESET buttons (tactile switches, actually)
• Remove the FAN ALERT - ESP32 connection and voltage divider
• Switch as many parts as possible to JLCPCB/LCSC parts
• Switch to discrete, one-way level shifters for CI, RO and RST

Planned

• Think about the OLED display connection.
• Switch to a barrel connector for power?
• make any necessary changes to the ESP32-BM1397 data connections

Is the usb port also for programming or debugging only?

[skot]

The USB port is for programming (via bootloader) and for serial debugging the ESP32. I'm not sure if you can do true debugging like JTAG

Hi Skot,
Did You abandon 2.3 version completely ?
Would be nice to complete the BM1397 project (with USB port)..
The barrel connector is fine, maybe overheating but in practice is completely sufficient.
-But your Bitaxe could be powered by the USB connector like it is so by Raspberry 4 . For it is sold 3A adapter.
USB 3 specification is power draw from 0-3 A for 5V

Debugging over USB can be done somehow :

which version should i use max v2.3 or max v2.2
in 2.3 you said that added USB port and tactile button but they are not available in 2.3
display connector also not available in 2.3

Hi, Yep, they left the bm1397 project completely.. no news after 2.3version The only one who solved/integrated the usb was one member, i think it was wantclue, or d-central (see youtube) . Ask them if they know more.. st 24. 4. 2024 o 6:41 vishaldagar96 ***@***.***> napísal(a):

I suggest then, you ask Skot about why it is not there :/ st 24. 4. 2024 o 8:40 vishaldagar96 ***@***.***> napísal(a):

Hello, from the fw 2.01 on the 1366, flash directly to the latest 2.3?
or little by little? first of all the esp-miner or the www.bin

Thanks for the help
