The ESP32 can pull as much as 250m A during RF transmissions, but we’ve generally measured it to consume around 150m A – even while actively transmitting over Wi Fi.
The output of the regulator is also broken out to the sides of the board – the pins labeled “3V3.” These pins can be used to supply external components.
The ESP32’s power and versatility will help make it the foundation of Io T and connected projects for many years to come.
The Spark Fun ESP32 Thing equips the ESP32 with everything necessary to program, run, and develop on the wonderchip.
In addition to USB and battery connectors, the VBAT, and VUSB pins are all broken out to both sides of the board.
As an alternative power source, the ESP32 Thing includes support for single-cell lithium-polymer (Li Po) batteries, which plug into the board’s white 2-pin JST connector.
In fact, the only required extra is a Micro-B USB Cable.
The ESP32 Thing’s USB interface can be used to both power and program the chip.
The Spark Fun ESP32 Thing is a comprehensive development platform for Espressif’s ESP32, their super-charged version of the popular ESP8266.
Like the 8266, the ESP32 is a Wi Fi-compatible microcontroller, but to that it adds support for Bluetooth low-energy (i.e BLE, BT4.0, Bluetooth Smart), and nearly 30 I/O pins.
