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.

Where to use ESP32 Wi-Fi & Bluetooth MCU

The ESP32 at the heart of the package has a Tensilica Xtensa dual-core 32-bit LX6 microprocessor, with 448KB of ROM and 520KB of SRAM (including 8KB of RTC memory), and a 1KB eFuse. The SIP module integrates 4MB of SPI Flash memory, although as the ESP32 can support up to 16MB it’s possible we might see that in future revisions. Wireless connectivity support is 802.11 b/g/n/e/i (802.11n up to 150 Mbps), alongside Bluetooth V4.2 (BR/EDR and Bluetooth LE support).

The module interfaces include an SD card, UART, SPI, SDIO, LED PWM, Motor PWM, I2S, I2C, IR, as well as GPIO, capacitive touch sensor, ADC, DAC, and an LNA pre-amplifier. The chip also has two onboard sensors—a Hall sensor to detect magnetic fields, and a temperature sensor. Its small footprint and reduced number of external components make it perfectly suited for wearables and other Internet of Things devices.
