WeMos LOLIN32 V1.0.0 based on ESP32 Rev1 Wifi Bluetooth Board. The board design is basically perfect. It takes more than a little inspiration from Adafruit’s Feather series
It has 4 MB flash memory onboard, a USB-serial adapter (cp210x), and a LiPo battery charger and connector. All the relevant pins are broken out and well-labeled, especially on the bottom.
