v2.1.0

Additions

• Add support for OTA updates
• Add power consumption section to README
• Improve schematic readability and add schematic pdf to /electronics folder

Bug fixes

• Fix pcb issues mentioned in last release

v2.0.0

Breaking changes

• Completely new Pcb, now created using KiCad:
  • ESP32C6 & BME280
  • Power Latch with Ultra Low Power Timer for Deepsleep current of under 200nA
  • Powered by single LiFePo4 AA rechargeable battery
• Completely new case, with no need for screws created with Onshape
  • Parts hold together with snap connections
• Updated firmware to handle configuration of Ultra Low Power Timer
  • Uses pioarduino to add pio support for ESP32-C6
  • Firmware configuration can now be resetted (Webserver will show again to configure again) (HOLD FCT button for 5 seconds while resetting)

Notes

• The current version of the pcb has an issue with C4. Instead of the cap you need to short the two contacts of the capacitor.
  -> Refer to the README for more information.

v1.1.0

Additions

• SECRETS.h has been replaced by a webserver which can be used for configuring the OpenESPTemp
  • This includes SSID+PW, POST URL and Token
• Starting with this release a precompiled binary is provided in the release Assets
  • Due to the webserver configuration workflow, settings are no longer compiled into the binary
  • README has been updated with instructions on how the flash the precompiled binary

v1.0.1

OpenESPTemp 1.0.1

Bug fixes

• The JST Connector is now located on the bottom for connection in the case
• The buttons where moved to the bottom and another kind of button was used to fix the spacing issue

Improvements

• Increased the size of the designators to be readable on the pcb
• Properly labeled the buttons, the UART connector and the JST connector

v1.0.0

The first release of the OpenESPTemp

Note that this design has a few flaws:

• The JST Connector is located on the top by default, which makes no sense for the case
  • The Connector needs to be soldered on the bottom of the pcb as shown in the README (the README is already updated)
• The spacing of the pads for the two buttons is to wide, so SMT machines cannot assemble them automatically
  (!README already shows a fixed version which is not fixed in this version!)
  • Instead they can be soldered by hand just fine
• The buttons are also located on the top which is not ideal as you cannot access them when the pcb is mounted in the case

Therefore I suggest to add a DNP in the BOM in the column Your Instructions / Notes to not get them assembled but assemble them yourself.
In case you want to use a Pogo Pin Adapter you might also add DNP to the Pin header.

DNP should then be added to the Items 5, 10 and 12 with the designators ESP_BOOT_SW2,ESP_RST_SW1, J1, UART:
