New Lolin D1 mini compatible, with ESP32-S2, USB-C : r/esp32
Aug 19, 2021 · Doh! I (wrongly) assumed that they designed the boards not only to be pin compatible with the shields but also pinout compatible. Pin 4 / 5 are the default I2C pins on the D1 Mini, but that maps to 33 / 35 on the S2. I knew it had to be something silly. Thanks for the help.
Wemos D1 Mini I2C Troubleshooting : r/Esphome - Reddit
Jan 7, 2022 · The D1, D2 pin names are arduino terminology which are meant to be independent of the mcu on the board. The gpio numbers are specific to the mcu. For the d1 mini here is a diagram that shows the mapping: ESP8266-WeMos-D1-Mini-pinout-gpio-pin
D1 Mini ESP32 vs ESP8266 Pinout - is the linked item compatible?
Aug 21, 2022 · I would like to use the linked board for a energy monitor but with an ESP32 based D1 Mini rather than a ESP8266. I've checked the pinouts and think it should be compatible with the ESP32 but just wanted to do a bit of a check with the good folks on reddit before I …
ESP32-S2 pinout - for those of you who are looking for an ... - Reddit
As for my hobbyist's needs, I used D1 mini for projects that require Wi-Fi access, but I run out of pins. Now I need at at least 18 to control various peripherals, so I thought why not to try S2. So many pins must be enough for everything (well, until I will have yet another stupid idea what else to connect to it).
Wemos D1 mini V4 first look differences : r/esp8266 - Reddit
Nov 17, 2022 · The footprint and pinout on the V4.0 are identical to the previous Wemos-minis, so there's no reason why not. They call the 5V pin Vbus now, but it still takes 5v in and drives the regulator for 3v3. I don't know how many manufacturers there are for V4, but the ones I have, and the ones I've seen tested, have better sleep performance,.
WEMOS TTGO Mini D1 ESP32 : r/esp8266 - Reddit
Dec 24, 2018 · The D1 mini pinout in pairs: RST - TX ADC - RX IO16 - IO5 IO14 - IO4 IO12 - IO0 IO13 - IO2 IO15 - GND 3V3 - 5V0 This board pinout in the white marked PINs: RST - TX SVP - RX IO26 - IO22 IO18 - IO21 IO19 - IO17 IO23 - IO16 IO5 - GND 3V3 - 5V0 I can reconfigure the digital GPIO pins from the firmware but the other PINs is same (SVP is also the ...
ESP32 D1 Mini information - Reddit
Dec 20, 2019 · Regulator is a little SOT-23-5 marked "4B2K" which I am yet to postively identify but googling it links to either a RT9193 or maybe XC6221 (edit: or ME6221), both appear to have the correct pinout, pins 1 and 3 are 5v and 6 is 3.3 out. I really want to identify it so if anyone knows what a 4B2K is please share.

Oct 10, 2022 · For the D1, D2, G and 5V pins we will use header and pin connectors soldered on the D1 mini and the mmWave sensor. The D0 - IO2 connection happens via a wire which is soldered on the D0 pad of the D1 mini and the IO2 pad of the sensor. Assembly images. Solder the header connectors and the single wire to the D1 Mini as below:
Help with wiring up an D1 Mini (ESP8266) : r/homeautomation
May 26, 2021 · "don't understand how the relay shield is on D1/GPI05 if it's stacked." Is a confusing statement. What do you think stacked means and what do you think "on D1/GPIO5" means? It means that if you stack them and solder all terminals together then the control terminal for the relay will be electrically connected to the D1/GPIO5 terminal of the ESP.
