easySwitchBox is part of the Microchip Get Launched 2019 design competition!

The easySwitchBox does one simple thing – it sends on\off signals to any relay, actuator, or other project. It can be used to trigger any event wirelessly and from a distance (even up to a couple kilometers using LoRa®). It’s easy to program using the Arduino IDE, and communication is secured by an authentication chip. The easySwitchBox not only makes your project more effective, it also looks more professional.

Nano Radio Shield

Some easySwitchBox kits ship with an Arduino Nano radio shield that allows you to easily receive signals from easySwitchBox using an Arduino Nano. This shield:

  • Will come with the same radio configuration as the easySwitchBox you order (RFM69-CW/HCW, RFM95)
  • Allows jumper wire access to all Nano pins, even with the Nano installed
  • Contains an Atmel/Microchip ATSHA204A crypto authentication chip (as does easySwitchBox)
  • Has an SMA connector for antenna (antenna is included)
  • Has an on-board 5 V to 3.3 V level converter for the radio and Flash
  • Features a microSD card slot

* Battery life depends on modem configurations of bandwidth, spreading factors, and coding rates

Quality and Versatility

RFM 95 has miles of coverage. RFM 69 is great for indoor use (for example: RFM69CW can easily cover large 5-story building). Since easySwitchBox is 100% compatible with Arduino IDE, anyone who loves Arduinos can use it in their projects. The easySwitchBox also comes with example code, to help get you started.

Finely-Tuned and Tested

Each easySwitchBox is tested and tuned while inside the enclosure and with a hand in front of it so that the resonance and Standing Wave Ratio (SWR) can account for these blockages.

Easy to Program

It has both open source hardware and software parts. The project is based on popular RFM 69/95 radios. There are lots of open source drivers and software available for RFM 433/868/915 MHz radios. It is easily programmable, using the popular ATmega328P, and is Arduino IDE compatible.

Security Features

For added security, easySwitchBox offers the option of using a secured handshake, backed by a Microchip/Atmel ATSHA204A crypto-authentication chip.

Professional-looking Enclosure

The enclosure is minimal, stylish, and sleek. The clean and professional case will elevate any project. It also mounts using the provided double-sided tape or screws through the back plate.

Support & Documentation

The easySwitchBox is proudly open source. See below for links to forums, mailing lists, and other documentation.

Manufacturing Plan

Components will be sourced from Mouser. PCBs will be made at well-known manufacturer PCBWay. We have used PCBWay for years and consider them our best supplier \ PCB manufacturer. They are not the cheapest, but their quality and manufacturing yield is perfect.
For prototyping, we have a low-volume manufacturing facility nearby in Minsk, Belarus that can handle assembly as well as prototype testing. We have now been through several iterations of prototyping for the 433 MHz version, and we have completed the 868 and 915 MHz designs.

*The FTDI adapter and clamp shown here are not included in the campaign pledges.

Fulfillment & Logistics

Crowd Supply will be handling the fulfillment and delivery of easySwitchBox items worldwide. You can learn more about their shipping methods in The Crowd Supply Guide.

Risks & Challenges

Hardware is hard, but we’ve tried our best to mitigate potential problems we could run into. Any unexpected delays will be communicated clearly and promptly to backers through our campaign updates.


  • Poor PCB Yield: There is a risk of PCB production issues when we order a larger batch. Unlike samples, production batches could have yield issues. If that is the case, the solution is another production run. An additional run would cause delays for our entire manufacturing process.

The local prototype manufacturing facility we plan to use greatly reduces the risk associated with product design and testing while prototyping and designing the PCBs.

  • Component Shortages and Shipping Delays: We encounter these from time to time and do our best to mitigate those risks by choosing the most reliable sourcing partners and a PCB factory we trust.


  • Frequency Range: The wide variety of the frequencies could present an additional challenge.
  • Antenna Design: The easySwitchBox antenna design is based on the successful TI design.

Working off a proven design is helpful, but the antennas themselves require a lot of “bench testing” to achieve maximum range. It can be a very time consuming process, because it includes testing with the enclosure and a human finger\palm.

  • Testing: Every single board coming from the manufacturer needs to be functionally tested. This can be time consuming, but needs to be done.
