TinyPICO NANO

by Unexpected Maker

TinyPICO NANO is the world’s smallest, fully-featured ESP32 microcontroller module - just drop it on your PCB and focus on your features!

Don’t be fooled by its size, TinyPICO NANO is a complete drop in microcontroller module - BYO USB connector!

The Specs

  • ESP32 PICO D4
  • Micropython
  • Espressif IDF
  • Arduino IDE
  • 32Bit Dual Core 240Mhz
  • 2.4GHz Wifi - 802.11b/g/n
  • Bluetooth BLE 4.2
  • 4MB SPI FLash
  • 4MB Extra PSRAM
  • USB + Serial/UART for programming
  • 700mA 3.3V LDO Regulator
  • LIPO Battery Management
  • Optimised power path for low power battery usage
  • VBAT Pin for Battery connection
  • Enable pin for LDO On/Off control
  • 27x GPIO broken out
  • Oh, it's tiny! Just 13mm x 27mm

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 deepsleep.

The Pinout

Unexpected Maker have broken out everything they could, including 6 of the Input only pins that are on ADC 1. They’ve even included an ENable pin to allow you to shut down the 3.3V LDO powering the ESP32 (enabled by default) and a STAT pin to connect the cathode of an external LED to for the battery charge state. LED anode connects to 5V.

It really really is small!

At only 13x27mm

TinyPICO NANO is the worlds smallest, fully featured ESP32 microcontroller board in a module format

All you need to add is a USB connector of your choice, if you need one!

What's it got?

Almost all of the goodies you know and love from the TinyPICO are here.

You’ll need to use paste & reflow/hot-air to solder the TinyPICO NANO to your PCB.

TinyPICO NANO is reflowed with SAC305.

Optimised power paths & deep sleep current

TinyPICO NANO has been designed with two isolated power paths: a 5 V path and a 3.3 V path. Any components that are not needed for operation via battery or via the 3.3 V power pin are isolated within the 5 V power path, and are totally shut down when no USB cable is plugged in.

In-fact, even the power LED is shutdown when no 5 V power source is present.

Deep sleep has been optimised for all development platforms, and although it has been seen to go as low as 10 uA, the official current rating in deep sleep is 18 uA.

Footprints & Schematic

Unexpected Maker have a few ECAD footprints available for the TinyPICO NANO. If you are using an ECAD package not covered in the link, let us know and we’ll see what we can do for you!

The schematic is also available in PDF format in the repo and here is a direct link

Certification

TinyPICO NANO ships uncertified. If you use a TinyPICO NANO on a project that requires certification, you’ll be required to also certify the WiFi and Bluetooth radios.
