Bump.
@ESP_igrr There are still no drawings with the dimensions to find for the dev boards.
Like permal said, these drawings should/could be uploaded to docs.espressif.com.

eStreamPlayer32 - Mediaplayer for Arduino IDE.
I made a mediaplayer for esp32 that plays webstreams and your local files from a http server.
The interface is completely web-based.
It compiles in the Arduino IDE.
To browse the local files you need to copy a php script to the http server.

Re: GPIO drive strength.
@bobtidey The resistor (I use 20K) gate -> ground is present. Thanks for the tip about IRF3708, I think I will buy and test some of those. @Saakje If you are using an NPN power transistor, then yes, you will need a resistor and you will pull current into the base. Do you maybe have some background i...

Re: GPIO drive strength.
If you are using an NPN power transistor, then yes, you will need a resistor and you will pull current into the base. Hi Saakje. I am using IRLZ44N mosfets so a gate resistor should be includeed in my opinion. While testing I drove the mosfets a while without gate resistors and no bad things happen...

GPIO drive strength.
I read about the increased maximum drive strength on GPIOs and went looking for an example. Could not find one and just tried some code on a MH-ET LIVE minikit. The code compiles and the esp did not blow up! void setup() { pinMode( LED0_PIN, OUTPUT ); pinMode( LED1_PIN, OUTPUT ); pinMode( LED2_PIN, ...

Unknown revision esp32? revision (unknown 0xa)
Today I received some new MH-ET mini kits . With esptool 2.3.1 ( on Linux Mint 17.2 Rafaela ) I get this output when I flash the chip: Connecting..... Chip is ESP32D0WDQ6 (revision (unknown 0xa) Features: WiFi, BT, Dual Core, VRef calibration in efuse The markings on the RF can are also a bit differ...

Re: Conflict WiFi with dallas temperature library for ds18b20 ???
No idea why the network scan would interfere. I do have some code which should run. https://github.com/CelliesProjects/dallas-webserver https://github.com/CelliesProjects/esp32-multi-DS18B20-task And check out stickbreakers OneWire repo . This lib solves a lot of OneWire problems, and the solutions ...

Re: Heltec ESP W32 Kit with OLED (beginner)
I have made a millisecond clock poc on a similar OLED.
Shows some basic concepts.

You probably need to change the pin definitions.
