## Description

ESP32 ESP-32 0.96" OLED Display WIFI-BT for Arduino AP STA Description: ESP32 has integrated antenna and RF Barron, power amplifier, low noise amplifier, filter and supply Management module. The entire solution is the smallest PCB area. The board is 2.4 GHz dual-mode Wi-Fi and Bluetooth low power technology, with a wide range of safe, reliable and scalable applications for the TSMC 40nm chips, power and best RF features. Features: high-performance price ratio, small size, easy embedding to other products powerful, with the support of the LwIP protocol, support three modes: using AP, STA and AP and STA LUA program support, easy to develop Package included: 1* ESP32 ESP-32 0.96" OLED Display WIFI-BT for Arduino AP STA

Review: Great board, one caveat. - Great little board! The one caveat is the board does not have the "auto reset" circuitry for flashing the firmware/uploading sketches, but upload MicroPython once and you can use the "ampy" tool to run scripts without rebooting! I just created a simple sketch for a game I play, just shows my "Energy, Nerve, Happiness, Life" on the OLED (see screenshot), works just like any other SSD1306 OLED. I personally prefer the white OLED to the blue on other brands. (commonly blue)
Review: Nice ESP32 board, but has PWM issues at low frequencies - This is a very nice ESP32 board. The integrated OLED display is super-convenient for debugging and IoT projects that can benefit from a display. Everything works as expected when coding via MicroPython, and GPIO operation is generally solid, but PWM output has some issues at lower frequencies (<5 kHz). This isn't a big deal for most applications, but servo motors operating at 50 Hz can't be driven using PWM -- I tried this with 4 different kinds of servos with no luck, and finally had to write a custom loop to manage the timing "by hand".

## Questions & Answers

**Q: What are the details on the screen? What is it's model number? What is its resolution?**
A: Okay so it took a lot of squinting but the model number o the screen is 9e6008a1.

I found an eBay listing saying that it is SSD1306 using I2C

**Q: I've got the wifi and display working fine, but can't get any I/O pins working.  Anyone have a pin out diagram?**
A: Here you go: https://github.com/FablabTorino/AUG-Torino/wiki/Wemos-Lolin-board-%28ESP32-with-128x64-SSD1306-I2C-OLED-display%29

**Q: What are the gpio marked touch for?**
A: The touch GPIOs are able to detect the touch of a finger. When you initialize them as touchpads like this in MicroPython:

from machine import Pin, TouchPad
up = TouchPad(Pin(input_up))

You can now read a value from the GPIO that will let you know if someone is touching it with their finger.

up_value = up.read()

If I remember correctly, the value is between 0 and 1024, and it kind of jumps around a bit. But when it falls below the midpoint of the range, you can be pretty sure somebody's got their finger on it.

You should be able to wire a metal pad to it as well, though I've never gone that far.

**Q: What voltage do I need to run off of batteries?**
A: Standard LiPo or 18650 battery (3.3V)

### ⭐⭐⭐⭐ Nice ESP32 board, but has PWM issues at low frequencies

### ⭐⭐⭐⭐⭐ Five minutes to IoT!
*by E***. on October 24, 2018*

Five minutes to IoT! This board is very easy to use with the Arduino IDE. 1) Add the additional board manager URL by going to File->Preferences 2) Add the ESP32 boards by going to Tools->Board->Board Manager and typing "ESP32" in the search bar 3) Select "WEMOS LOLIN32" from Tools->Board. Ensure you have the correct COM port. 4) Pick a sketch from File->Examples and upload to the board. I used "SimpleTime" which connects to your wifi (enter SSID and password on lines 4 and 5 of the sketch) and gets the current time using NTP. It then echoes this time to the serial monitor. Bottom right shows the client list from my router showing the ESP32 has connected. Great little board for all your internet-enabled projects, the built in display is just awesome for debugging and status.
