Espressif Systems’ ESP-32-PICO-D4 is a System-in-Package (SIP) module that is based on the ESP32, providing complete Wi-Fi and Bluetooth functionalities. The module has a size as small as 7,0 x 7,0 x 0,94 mm, thus requiring minimal PCB area, and it 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 ultra-low power technology. The ESP32-PICO-D4 integrates all peripheral components seamlessly, including a crystal oscillator, Flash, filter capacitors and RF matching links in one single package. Given that no other peripheral components are involved, module welding and testing is not required either.
With its ultra-small size, robust performance and low energy consumption, ESP32-PICO-D4 is well suited for any space-limited or battery-operated applications, such as wearable electronics, medical equipment, sensors and other IoT products.
