#### **Development Platforms & Software Documentation**

TinyPICO ships with mainline MicroPython pre-installed and supports Arduino IDE and Espressif IDF, so you have the flexibility to code the way you want.

I have been working hard behind the scenes on MicroPython and Arduino C++ helper libraries for TinyPICO as well as collecting and even writing MicroPython libraries for all the hardware we use on our shields.

I have basic coding examples on our TinyPICO website and all of our libraries are being added to the [TinyPICO GitHub repository](https://github.com/TinyPICO).

#### **Optimised Power Paths & Deep Sleep Current**

TinyPICO 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 & charge LEDs are shutdown when no 5 V power source is present.

Deep sleep has been optimised for all development platforms, and though we have seen it go as low as 10 uA, our official current rating in deep sleep is 18 uA.

**Note:** TinyPICO includes an on-board APA102 RGB LED that has a quiescent current of 1 mA.

Thankfully we have a solution for deep sleep. GPIO13 controls the power to the APA102 using a PNP transistor via a high-side switch, so taking GPIO13 high shuts down power to the APA102. It’s essential to do this before going into deep sleep to ensure the lowest current draw possible.

In MicroPython, it’s also required to shutdown GPIO2 and GPIO12 (DATA and CLK for the APA102) as MicroPython uses IDLE HIGH as the default clock state, so you can get current leakage via the CLK or DATA, even with no power to the APA102 directly. We have created some helper functions for you in our TinyPICO MicroPython helper library to make this easy.

#### **Package Contents**

Each TinyPICO comes in an anti-static bag that includes:

- 1x TinyPICO
- 1x Set of male headers
- 1x JST PH connector
- 1x Printed pinout reference card

The headers and JST connector come loose, and require soldering if you plan to use them.

#### **TinyPICO and Heat**

The Espressif PICO-D4 is a very powerful SIP (System In a Package) for its size, and when running Wi-Fi continuously it gets hot, and because the TinyPICO is small, there is not a lot of place for heat to transfer to.

This is nothing to be alarmed about though. Even when running hot, everything is well within spec. It’s just something we wanted everyone to be aware of.

If you need to keep Wi-Fi active for long periods of time, like for a soft-ap setup, make sure you don’t enclose your TinyPICO in a small case that has no air flow, and maybe even consider adding a small heatsink to the board to help with heat transfer.
