TinyPICO Nano is the world’s smallest, fully-featured ESP32 microcontroller module - just drop it on your PCB and focus on your features!
No compromises! The module packs a massive 700mA 3.3V regulator, on-board battery management, 4MB of extra PSRAM and 27 GPIO! TinyPICO Nano is tuned for ultra low current use, dropping below 20uA when in deep sleep.
Don’t be fooled by its size, TinyPICO Nano is a complete drop in microcontroller module - BYO USB connector!
TinyPICO Nano V4 is the same TinyPICO Nano as the original. The Ignion antennas used on earlier versions have been discontinued, so V4 now includes a new high gain 3D antenna and RF network.
