Reixa LoRa Keyfob
Reixa is an ultra low power dual-radio keyfob: a LoRa 868 MHz link and a 433 MHz sub-GHz transmitter on a single 45 x 75 mm, 4-layer board, running straight off two AAA cells.
Custom electronics, from first schematic to production.
Guionics is an electronics design studio in Barcelona. We design boards and firmware for medical devices, robotics and IoT, and stay with each project through prototyping, certification and manufacturing.
Selected work
All projects
R45 PCB Motor
The R45 PCB Motor is a new modular PCB motor concept that allows tuning of performance by simply selecting a different stack of motor PCBs.
R45 PCB Motor Driver
The R45 PCB Motor Driver is a high-performance BLDC driver specifically developed for our in-house designed R45 PCB Motor.
R20 PCB Motor
The goal of this project was to create a small, highly efficient, and extremely affordable PCB Motor. The “comb” design allows for greater efficiency and torque density.
IoT HDMI Mux
The IoT HDMI Mux integrates an ESP32-C3, a 2.4GHz antenna and a 2:1 HDMI mux IC in order to create a connected HDMI mux.
