Wemos D1 R32 Development Board ESP32 4MB Flash Wifi Bluetooth BLE

The Wemos D1 R32 is an Arduino Uno form factor ESP32 dev board. With a clock speed up to 240Mhz and one core dedicated to wireless functions, it is MUCH faster than the ESP8266. Perfect for arduino, NODEMCU or micropython projects that need more 'oomph!'.
NOTE: This is a 3.3V device. So may not work with all arduino shields.

Working Voltage: 3.3V DC (GPIO working on 3.3V,use logic converter if need 5V)
Input Voltage: 5V - 12V DC (via jack dc,rekomendasi 9V)

Analog In max 3.2V
Wifi: 802.11 b/g/n/e/i (802.11n up to 150 Mbps)
Bluetooth: v4.2 BR/EDR and BLE
Memory: 520KB Flash: 32Mb (4M bytes)
Current: 250mA (max)
Current: 0.15mA (sleep)
Current: 20mA (ON but no wifi)
Temperature: -40C > 85C
