HiLetgo ESP32 OLED WiFi Kit ESP-32 0.96 Inch Blue OLED Display WIFI+Bluetooth CP2012 Internet Development Board for Arduino ESP8266 NodeMCU

Q: What soldering is involved, smt components or just great pins?

All that needs to be soldered are the header pins. It is a bit tricky on the side with the display ribbon cable, so proceed with caution.

Q: I haven't been able to find a battery that plugs into that little tiny connector. Pointers?

1.25mm JST connector. These work: Letool®30 Pairs JST 1.25mm 2 Pin Micro Male Female Connector Plug 80mm Wires Cables https://www.amazon.com/dp/B013JRWCBU/ref=cm_sw_r_cp_apa_i_WzDpDb3PJBTND

Q: What is needed to power it? Can it be usb otg cable connected to laptop?

USB Micro charger with around 0.5 amps but better with full 1 amp capability. When can you connected to a PC made in the last 10 years, it should have enough to supply proper current using the same Micro USB cable I mentioned.

Q: Can you write to the display or is it just for builtin connection processes?

You can write to the display as you would any OLED with Arduino. The graphics are quit nice for a small screen.

Quality ESP32 board with built in OLED

Quality little board. Very compact which is useful and the onboard OLED is great for status display or debugging info.Worked straight away for me using Arduino IDE 1.8.9 and the ESP32 release installed by boards manager (v1.0.2) from the official ESP board manager url.
