Electronics hardware development

SP Engineers LLC provide electronics hardware development services from prototype level devices up to massproduction ready products. Depending on product’s required functionality, we are able to create PCB design, embedded software, server software, mobile applications and web-based administration systems. We provide consultation services for production chain creation and create required documentation for certification for retail sales (e.g. CE).

SP Engineers LLC can also take care of products manufacturing – as a customer you only need to let us know required quantity of products and we can deliver them to you or to your end-customer.

Our development office is situated in Tallinn, Estonia. Our sales and support offices are in Tallinn, Estonia and London, UK.

We have been developing electronics devices since 2014. Our engineers have over 10 years experience in developing electronics hardware and software. Here are some of devices we have made for our customers:

Negative pressure monitoring device

Negative pressure monitoring device is meant to be used during demolition works in construction industry. All measurement data is sent to server-based application over GSM. Web-based user interface allows to get overview of device measurements. Device can be set up conveniently via mobile phone.

Etnobird smart wild bird feeder

Battery powered smart wild bird feeder detects wild bird visits and takes high quality photos of birds. All photos are instantly published to web server over Wifi and can be seen via mobile apps. Seed sensor keeps user aware if seeds are starting to run out and feeder needs refilling.

Goods tracking solutions
Compact trackers report their location on predefined time intervals over GSM network. Battery powered trackers have optimized power consumption logic, which allows them to have several weeks long lifetime. Web-based user interface allows to see trackers route on a map.

Indoor positioning solutions

Bluetooth Beacon-based indoor positioning solution for smart homes allows to detect user’s mobile phone with room-accuracy.

NBIoT communication module for soil’s moisture meter
NBIoT based communication module for soil’s moisture meter for usage on fields and roads.

Cable connection tester
Industrial cable connection tester measures cable connections’ resistance and correctness. LED indicators outline faulty connections.
