New 3.5" Color LCD display

We are currently building the first batch of full color graphical displays with WiFi.

@Ken We agree, the first firmware 5.1.0 was essentially a proof of concept, attempting to approximate the old display. 


The interface is by no means final, we took static images of the web interface. Future versions will use the LVGL.


We plan to add additional screens that will automatically change, showing the the session log, usage and history. In addition we are working on an enclosure with a cutout, seals and a touch display. The watertight seals are really tricky. The hardware is capable of display sleep, it is on the list.

Music to my ears.

Is it possible to confirm if the new LCD is a direct replacement for the old LED board and Wifi module?


My wifi module fails to perform a factory reset on the password and I figured if I was going to be going into the box to perform a manual reset, that I would go ahead and upgrade to the LED to the LCD with built-in wifi.

@Levi The NEW TFT LCD replaces the WiFi. Technically you could continue to use the older 2 line text LCD or the LED based displays. If you have the polycarbonate enclosure with the 2 line display, we have a lid only option that has the proper window for the new much larger display. If you have the older "portable" enclosure with the LED light only (no display) you would need to replace the whole enclosure and the size is too small.



That makes sense. I have the two line LED right now with the polycarbonate enclosure with the malfunctioning wifi module as mentioned. I'll take a look on the store to see if I can find the lid and add that to the card with the TFT LCD Display.


Assuming that the LCD display and wifi come pre-flashed with the latest firmware?



Any news on when the firmware can be updated for the new large LCD?

@ Ken


The current repartition process for the TFT LCD in the short term requires a USB => Serial adapter and esptools (requires Python and pyserial). 


Download the 5.1.2 - openevse_wifi_tft_v1.bin, bootloader_16mb.bin and partitions_16mb.bin from

https://github.com/OpenEVSE/openevse_esp32_firmware/releases/tag/v5.1.2


Connect the module to the USB => Serial adapter, then put the module in bootloader mode by holding BOOT and then pressing RESET then release BOOT


Run the command:


esptool --baud 921600 --before default_reset --after hard_reset write_flash -z --flash_mode dio --flash_size=detect 0x1000 bootloader_16mb.bin 0x8000 partitions_16mb.bin 0x10000 openevse_wifi_tft_v1.bin

On Thursday, I received my TFT LCD and cover for upgrading my old OpenEvse Kit.

It came pre-flashed 

I love It !!

@ OpenEVSE Support I can’t seem to enter bootloader mode using the boot and the reset buttons and the instructions above. Maybe the boot button doesn’t work on my board? The reset button resets the screen and just boots it up normally. But holding the boot button and pressing the reset button just resets the screen and boots back up.
@OpenEVSE Support I’m having some trouble putting the 3.5” TFT LCD board into bootloader mode. Maybe the boot button doesn’t work on my board? When I follow the steps mentioned in a previous post, the screen just resets and boots back up normally. The reset button appears to work. Are there any workarounds?
@ OpenEVSE Support Never mind my previous question. I found the GPIO0 pin on the ESP32 and shorted it to simulate the boot button press and then pressed the reset button. I was able to get into bootloader mode and update to 5.1.2.
