Custom electronics and embedded software
for connected products.
Berlin-based engineering studio delivering custom PCB design, rapid prototyping, and embedded firmware — from initial concept to series-ready hardware.
Custom electronics and embedded software
for connected products.
Berlin-based engineering studio delivering custom PCB design, rapid prototyping, and embedded firmware — from initial concept to series-ready hardware.
From early-stage consulting to production-ready hardware and firmware.
Architecture reviews, feasibility studies, and hands-on technical guidance — from initial scoping to de-risking a design mid-development.
Full hardware lifecycle — schematic capture, PCB layout, bring-up, and production support for mixed-signal, RF, and power electronics designs.
Bare-metal, RTOS, and embedded Linux — from ARM Cortex-M microcontrollers to application processors, covering driver development and system integration.
A selection of hardware and firmware work from the studio.
A development platform for energy-harvesting devices with four stackable boards. The SDK includes a battery-free runtime, device drivers, two network protocols, and example applications from "Hello World" to hotword detection.
A system for replaying reproducible light traces. A BeagleBone with a custom cape controls current through a high-power LED. The firmware retrieves light traces from SD card or via TCP/IP, adjusting LED current at up to 1 kHz.
An expansion shield interfacing an STM32 Nucleo board with industrial manufacturing machinery. Features multiple isolated power supplies, an industrial Ethernet controller, and a variety of isolated communication interfaces.
Nessie Circuits was founded in 2021 by Dr.-Ing. Kai Geißdörfer, an embedded systems engineer with over a decade of experience in low-power IoT hardware. The studio specializes in energy-harvesting systems and wireless sensor nodes, working with suppliers and collaborators in Berlin and internationally.
Customers include universities, research organizations, and companies across Europe, North America, and Australia.
Research institutions and industry customers across three continents.
