Wemos – the company behind the cool Wemos D1 mini ESP8266 board – has now launched its first Espressif ESP32 development board with LoLin32 equipped with ESP-WROOM-32 module with 4MB flash, a micro USB port, and a battery header.
Wemos Lolin32 specifications:
- Wireless Module – ESP-WROOM-32 based on Espressif ESP-32 dual core processor @ 240 MHz with 4MB flash
- Connectivity – 802.11 b/g/n WiFi + Bluetooth LE
- I/Os
- 26x digital I/Os
- 12x analog inputs
- UART, I2C, SPI, VP/VN, DAC
- 3.3V I/O voltage
- Breadboard compatible
- USB – 1x micro USB port for power and programming/debugging
- Power – 5V via micro USB + battery header for Lithium battery (charging current: 500mA max)
- Dimensions – 5.8 x 2.54 cm
- Weight – 5.8 grams
The board is not compatible with Wemos D1 mini (34.2 x 25.6 mm) and shield, but offers a more powerful solution with Bluetooth LE, battery support, and more I/Os. The Wiki is still work-in-progres, and there’s no that much information on the page yet.
Wemos LoLin32 can be purchased for $6.90 + shipping ($8.66 in my case) on Aliexpress.

Nice. Any idea which revision they are using?

Not sure. I would not worry too much about those bugs, unless your application is specifically affected by one or more of them. Processors often have a list of errata.
@GunterO almost definitely version 0. Version 1 is barely starting production. At some point it will probably transparently shift to version 1 and be impossible to tell, so hopefully they aren’t making tons that will stay in inventory all year.
Already out of stock on Aliexpress.

Got mine today, trying to flash Blink something with the Arduino IDE… the board does not seem to have an onboard led…

On board Led is on pin 5.
