ESP8266 Nodemcu with 0.96 OLED extended Temperature and Humidity Development Board

ESP8266 NODEMCU 0.96 OLED Temperature Humidity Development Board Weather Station WIFI AttackFeature:1. The five key buttons are controlled by FLATH,RSET,D5,D6 and D7 respectively. 2. OLED SDA and SCL received D1 and D2 respectively. 3. Five digital pins can be configured separately the write/read/interrupt/PWM/I2C/one – wire supported 4. 1pc AD input. 5. Integrated 18650 battery charging and discharging system. 6. Micro USB input. 7. Compatible for Arduino. 8. Compatible for NodeMCU. 9. Wide voltage input range 5V~12V. 10. A switch can control the power supply of 18650. 11. 1pc programmable LED(D0). 12. Charging protection, Discharge protection. 13. The design concept originates from the open source project NodeMCU. The development board integrates 18650 charging and discharging systems with a charge and discharge protection, and integrates a OLED and five – direction button to facilitate the development. 14. The operation is consistent with NodeMCU, and a programmable LED is added. It can be controlled by GPIO16 and display the running state of 8266. Integrated with OLED and five key buttons, more convenient for development.Specification:Model:ESP-8266 Color: Black Charging Protection: Yes Discharge Protection: Yes Compatible for NodeMCU Wide Voltage Input Range: 5V~12V Charge Current: 500 mA Size(L*W*H): approx.102 x 30 x 20 mm/4.01 x 1.18 x 0.78” Display Size: 0.96 InchWarm Tips:1. Please do not burn the program during charging. When you burn the program, please unplug the battery and verify the switch is in ON position. 2. This product does not contain 18650 batteries.If the battery is in the wrong direction, the charging chip will be destroyed. 3. Recommend the use of 5V 500mA charging charger, more than 5V 1A there will be fever, does not affect the normal work, but in the process of charging charging chip do not touch or carry, the measured charge charging will rise to about 60 degrees with the diode chip,no heat during normal working hours, rest assured to carry.Note: Please allow 1-3mm differs due to manual measurement. Due to the different display and different light, the picture may not show the actual color of the item. Thanks for your understanding.Package Content: 1 x ESP8266 Mini-WiFi NodeMCU Module with 10 Pins
