Custom Board: Can't connect to WiFi

My board only manages to connect to wifi if the UART flasher is also connected, if I disconnect the UART and leave only the main power connected then the wifi does not connect.

ESP32-WROOM-32D (4MB HIGH TEMP) alternative

ESP32-WROOM-32E-H4 might be a suitable replacement, with likely the same (or similar) footprint and operating temperature range.

ignores heater temp limit

seems to ignore the heater temp limit and goes to 100c ,built as normal except for using 2 Adafruit SHT31 as in and out sensors,

A fatal error occurred: Failed to connect to ESP32: No serial data received.

I'm experiencing a error:
A fatal error occurred: Failed to connect to ESP32: No serial data received.
I connected using FTDI232
3V3 - 3V3
TX - RX
RX - TX
GND - GND

Could it be that the U3 component is MIC5365-1.8YD5-TR instead of 3V3?

(R4) component Also missing is the Bill of Materials

I noticed that the R4 component is missing, Could you please provide the name of the component needed?

PID values when 'Using HEATER as target temperature' returning negative

Hi Sasa, thanks for sharing this project and make it available to everyone :)

I am trying to setup the whole project since a while now, I am not a code expert so my efforts to fix some bugs are reaching a limit.

One situation that is that when the max_heater_temperature reaches the set value the PID values starts to get negative and the calculated PWM values shoot to the max and the heater keeps ON.

Am I missing something?
I am trying to create a branch and contribute for this project as soon as I understand git better 👍

Custom manufacturing package for PCBWay

Hi, the file for parts List (BOM) and Centroid file must be in xls,xlsx or csv, so I can order only the PCDB with gerber file.
Can you create this 2 missing files, please.
Best regards.
