ESP32-PICO-D4 BLUETOOTH & WIFI 2.4GHz~2.5GHz QFN-48-EP(7×7) RF Transceiver SMD IC

Description

ESP32-PICO-D4 BLUETOOTH & WIFI SMD IC ESP32-PICO-D4 is an ESP32-based System-in-Package (SIP) from Espressif. The new ESP32-PICO-D4 SIP combines an ESP32 SoC, crystal oscillator, filter capacitors, RF matching links, and 4MB flash, into a single 7mm × 7mm QFN package. Including the passive components in the design means that the new QFN package needs very little external support to be used on our own PCB. 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.
