Page 3: Module Overview
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. - Page 4 • Cameras for Video Streaming • Smart Agriculture • Over-the-top (OTT) Devices • Audio Applications • Speech Recognition • Health Care Applications • Image Recognition • Wi-Fi-enabled Toys • Mesh Network • Wearable Electronics • Home Automation • Retail & Catering Applications Espressif Systems...

- Page 8 • Firmware can configure register bits to change the settings of ”Voltage of Internal LDO (VDD_SDIO)” and ”Timing of SDIO Slave”, after booting. • The operating voltage of ESP32-PICO-V3-ZERO’s integrated external SPI flash is 3.3 V. Therefore, the strapping pin MTDI should hold bit ”0” during the module power-on reset.
