  • Update: ESP(32)-01 Programmer

    Thomas Buck11/23/2020 at 16:45 0 comments

    The first version of the ESP(32)-01 Programmer was build. Due to a pinout error, the USB-Connector (a Throu-Hole-Device, so no patch wires needed) must be soldered to the backside of the PCB. The Bug has been fixed in todays uploaded documentation and gerber files. Nevertheless, the gallery-pictures show the "buggy" setup.

    Next steps: Test the board.

what are the improvements with this in numbers?

A lot of resin 3D printers have a slot for a ESP-01 module but it’s too slow to actually do anything of use with one so they’re generally left unused, maybe this is the solution?

The ESP32 has two cores instead of just one, it clocks with twice the frequency (160 MHz instead of 80 MHz) and supports Bluetooth and WLAN while the ESP8266 has only WLAN.

The ESP32 has 512 kB RAM, while the older ESP8266 has only slightly above 100 kB (if I read the datasheet correct). The Flash Chip used here has 4MB compared to the 512k or 1M of the standard ESP-01 modules.

Conclusion: Yes, significant more processing power and memory. If someone is willing to give it a try, I would be very pleased and provide him/her one of these Modules.

  Are you sure? yes | no

I would be happy to give it a try, my resin printer (Ld-002r) has a chitu L v3 board in it which is ESP-01 compatible 

  Are you sure? yes | no
