1.2 Description
The ESP32-PICO-V3-ZERO is a module that is based on ESP32-PICO-V3, a System-in-Package (SiP) device. It
provides complete Wi-Fi and Bluetooth
®
functionalities. The module integrates a 4 MB SPI flash.
At the core of this module is the ESP32 chip, which is a single 2.4 GHz Wi-Fi and Bluetooth combo chip designed
with TSMC’s 40 nm low-power technology. ESP32-PICO-V3-ZERO integrates all peripheral components seam-
lessly, including a crystal oscillator, flash, filter capacitors and RF matching links in one single package. Module
assembly and testing are already done at SiP level. As such, ESP32-PICO-V3-ZERO reduces the complexity of
supply chain and improves control efficiency.
With its ultra-small size, robust performance and low-energy consumption, ESP32-PICO-V3-ZERO is well suited
for any space-limited or battery-operated applications, such as wearable electronics, medical equipment, sensors
and other IoT products.
