Active high. 10 GND GND N TI 2 AL It is recommended the maximum output current a power supply provides be of 500 mA or above.
3. Functional Description ! 3.1. Functional Description TI AL 3. CPU The ESP8285 integrates a Tensilica L106 32-bit RISC processor, which achieves extra- low power consumption and reaches a maximum clock speed of 160 MHz. The Real-Time Operating System (RTOS) and Wi-Fi stack allow 80% of the processing power to be available for user application programming and development.
3. Functional Description ! TI AL 3.4. Interface Description Table 3-1. Interface Description Pin Functional Description PWM IO12 (R), IO15 (G), IO13 (B) Currently the PWM interface has four channels, but users can extend it to five channels. PWM interface can realize the control of LED lights, buzzers, relays, electronic machines, etc. IR IO14 (IR_T), IO5 (IR_R) The functionality of the infrared remote control interface can be realized via software programming.

Power Consumption TI The following power consumption data were obtained from the tests with a 3.3V power supply and a voltage stabilizer, in 25°C ambient temperature.
4. Electrical Characteristics ! 📖 Notes: ① Modem-sleep mode is used in the applications that require the CPU to be working, as in PWM or I2S applications. According to 802.11 standards (like U-APSD), it shuts down the Wi-Fi Modem circuit while maintaining a Wi-Fi connection with no data transmission to optimize power consumption. E.g. in DTIM3, maintaining a sleep of 300 ms with a wakeup of 3 ms cycle to receive AP’s Beacon packages at interval requires about 15 mA current.
