ITEM NAME:ESP8266 0.96 OLED temperature humidity development board wIFI attack for NO S7N7 ESP8266 0.96 OLED temperature humidity development board wIFI attack for NO S7N7 Product Description: The development board integrates 18650 charging and discharging system, with charge and discharge protection, and integrates a OLED and five directional buttons to facilitate the development. This baby operation and NodeMCU consistent, increased a programmable LED, can use GPIO16 to control, display 8266 running state and other functions. OLED and five directional buttons are integrated, which is more convenient for development The five directional buttons are controlled by FLATH, RSET, D5, D6, D7 respectively OLED's SDA and SCL receive the D1 pin and the D2 pin respectively 5 Digital pins can configure write/read/interrupt/pwm/I2C/one-wire supported respectively 1 AD inputs 18650 battery charging and discharging system is integrated Micro-USB input Arduino compatibility NodeMCU compatibility Wide voltage input range 5V~12V 1 switches can control whether the 18650 power supply 1 programmable LED (D0) Charging protection Discharge protection Please do not burn the program in the process of charging, when you burn the program, please unplug the battery and confirm the switch in the position of ON colour: black Material: plastic size: 104*30*14mm Package Contents: 1 x ESP8266 NODEMCU 0.96 OLED extended temperature humidity development board meteorological station wIFI attack Note: This product does not contain 18650 batteries, the battery can not be installed back, otherwise it will burn the charging chip! Recommend the use of 5V500MA charging charger, more than 5V1A 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. Only the above package content, other products are not i.OLED's SDA and SCL receive the D1 pin and the D2 pin respectively. 18650 battery charging and discharging system is integrated. Note: This product does not contain 18650 batteries, the battery can not be installed back, otherwise it will burn the charging chip!
