Low power reference device for tracking and controlling the real world.

Here's how the resourciboard came about.

  • Digital Signage

    Researched a low cost, replaceable linux device for a new digital signage platform, based off a Raspberry Pi. The Raspberry Pi was only new at the time and didn't have the software required, so other hardware was used instead.

  • Network monitoring tool

    Changed to Arduino based, restricted it to non-display and relay control, proved web connectivity via ethernet board, expanded with a few more sensors and a web based configurator, and finalised an enclosure. Initial pcb design and fabrication, and assembly testing.

  • ESP32-cam power cycle timer

    Based off a 555 chip with a few discrete components, using leftover enclosures from initial project.

  • Timer board changed to ATTiny85

    Allow for more accurate timings, added wifi connectivity via ESP12F to send sensor data without the ESP32-Cam, created cloud app to send and receive data, initial pcb layout

    See the technical bits
  • ATTiny85 expanded

    Added bios-like functionality, added dedicated app chips, power finalisation, pcb finalisation and initial print

    Working it all out
  • Sub board theory, prototype

    Added the idea of making this board and its power options the base for sub boards to give it much more capability.

  • Sub boards

    Designed a number of sub boards for dedicated applications for the launch

    Sub boards
  • Mass production

    Assembly order and component testing, to get costs and stability

    Mass production
  • SaaS, application firmware

    With the device proven and costs worked out, fixed up a few issues within the firmware and got the SaaS working nicer


React on data from cloud sources, or other ResourciBoards

Show scrolling up to date news feeds on oversized segmented led displays. Display a coloured led status when the temperature drops or a gate is opened.

Sub boards expand the functionality of the ResourciBoard for specific applications

Indoor/Outdoor webcam

Weather resistant, self uploading, change detection

Shift Outputs

Stackable, low power signals, high current sink, light grids/matrix, text displays, lighting sequences

Giant Alphanumeric Display Neon style sign

Tracking with GPS

Rechargeable, water resistant, as little as each minute

Sense everything

Status indicator, temperature, light, doors/gates, movement. Kit form

Trigger when a door is opened/closed, or when an object is moved.

Oled / I2C

Demonstrating the ability to communicate with I2C peripherals. Oled status display. Kit form. QR Codes


Ideal for queue/ticketing applications. Trigger rechargeable ResourciBoards with a simple tap.

Integrate with Alexa & Emails

Ask Alexa the status of a device or to set a device to display your words. Receive emails when a device detects movement or a significant change.

¹input voltage limit dependent on heat dispersion available

²3.3v operation only

³current limited due to requirement of boost

⁴boosted, or no boost for extra low power operation (no recharge available)

⁵requires dedicated li-ion charging board

⁶depending on battery brand, longer delays between updates required, long initial recharge period

IO pins and their abilities overlap with eachother limiting the amount of peripherals

Only one power source can be provided at one time

Battery type practicality is determined by the peripheral current requirements
