Zero2Go Omini Rev2 is Here!

Zero2Go Omini Rev2 is released today! This is the second revision of Zero2Go Omini and it looks very similar with the first revision. Because the connectors, switch and LED are at the same locations, the new revision and old revision are almost physically interchangeable (except the USB type C connector).

Zero2Go Omini Rev1 and Rev2

What’s New?

One obvious change is that Zero2Go Omini Rev2 uses USB type C connector instead of micro USB connector. USB type C connector is easier for connection and can bear higher current.

You may also notice that newer revision has an unpopulated 3-pin header on the left ledge of the board. It is the VIN-GND-VOUT header which allows you to:

  • Add additional channel(s) to the board (using VIN and GND)
    Additional channel
  • Using Zero2Go Omini to control other devices (using VOUT and GND), for example a 5V relay.

More details about this VIN-GND-VOUT header can be found in the user manual.

The new revision uses the same firmware and software like the old revision.

Price and Where to Buy?

Zero2Go Omini Rev2 has the same price as the first revision, which is €15.72 (about 13.51GBP / 18.74USD / 23.12CAD).

You can order it from our e-shop or you may be able to order it from our resellers soon.

How About the Rev1?

Zero2Go Omini Rev1 will be discontinued.

At the time being we still have some of them in stock, you can order them if you like micro USB connector more.

New Product! Zero2Go Omini is Here!

Today we proudly announce our new product: Zero2Go Omini!

What is Zero2Go Omini?

Zero2Go Omini is the second member in the Zero2Go family. Just like the first generation of Zero2Go, Zero2Go Omini is a Raspberry Pi Zero sized (or pHAT shape)  and it can work as wide input range power supply for Raspberry Pi.
Zero2Go Omini supports all Raspberry Pi models that has the 40-pin GPIO header, including A+, B+, 2B, 3B, 3B+, Zero and Zero W.

What’s New?

Zero2Go Omini inherits the main features from its ancestor, and introduces a lot of exciting new features:

Multiple Input Channels

The first generation of Zero2Go has only one input channel and all input connectors are linked in parallel, which disallows you to connect multiple power supplies to Zero2Go at the same time. The new Zero2Go Omini has 3 separated input channels (A, B and C), so you can connect up to 3 different power supplies to it. All input channels can accept 3.5~28V DC, and Zero2Go Omini will automatically use the one with highest voltage.

Auto Step-Up / Step-Down

The first generation of Zero2Go only supports “pass-through” and “step-down”. The new Zero2Go Omini  supports “step-up” and “step-down” and it will switch between these two modes automatically. When input voltage is below 5.5V, the step-up engine will be used; otherwise the step-down engine will be used. You can tell which mode is currently used by checking the LED on Zero2Go Omini: blue means step-up/pass-though, green means step-down.

Monitor Input Voltages

After running the software for Zero2Go Omini, you can read the voltage value on each input channel.
The voltage values can be accessed via I2C interface, so you can also write your own program to read them.

Working as Uninterruptible Power Supply (UPS)

Now it is possible to specify a low-voltage threshold and a recovery voltage threshold to Zero2Go Omini. Zero2Go Omini will gracefully shutdown your Raspberry Pi when all input voltages are below the low-voltage threshold, and will turn on your Raspberry Pi when input voltage is higher than the preset recovery voltage threshold.
This feature is very useful for applications powered by battery, and with proper configuration Zero2Go Omini can work as a Uninterruptible Power Supply (UPS). You can find more details in the user manual.

MCU onboard

Zero2Go Omini uses an ATtiny841 micro controller. and thanks to that, it has very low standby current (0.1~0.9mA, depends on input voltage).
Also the MCU onboard allows us to define rather complex behavior for Zero2Go Omini. If you have ever used Witty Pi or the first generation of Zero2Go, you know none of them can work with NOOBS, because NOOBS delays the booting and that cause the power cut before actual booting happens. Zero2Go Omini doesn’t have this kind of limitation, it can work very well with NOOBS because it wouldn’t monitor the TXD pin before the booting is finished.

Where to Buy?

You can buy it now from our online shop. Our resellers may also start to resell this product soon.

New Product: Zero2Go can power your Raspberry Pi in many ways!

Some customers have asked us if we have a product that can do power switch like Witty Pi 2 and accepts higher input voltage, now we proudly announce that we have one!
Zero2Go is a Pi-Zero sized power supply board that can accept 5~26V input and output 5V for your Raspberry Pi. It also has a button on board, so you can turn on and off your Raspberry Pi with a single tap (just like Witty Pi 2).
Thanks to the wide range of input voltage, Zero2Go can power your Raspberry Pi with many kinds of power sources, such as power bank, Li-Po battery pack, solar panel, car battery or different kinds of power adapters etc.
You can use the pogo pin connector (included in package) to connect Zero2Go with Raspberry Pi without soldering.
Or you can solder a 40-pin header (not included in package) on Zero2Go to connect it with other models of Raspberry Pi:
