Prototyping Solutions For Embedded Systems
The espBerry DevBoard combines the ESP32-DevKitC development board with any Raspberry Pi HAT by connecting to the onboard RPi-compatible 40-pin GPIO header.
The purpose of the espBerry should not be perceived as a Raspberry Pi alternative but as extending the ESP32’s functionality by tapping into the vast offerings of RPi HATs in the market and taking advantage of the multiple and flexible hardware options.
The espBerry project continues to integrate an ever-increasing number of existing RPi HATs and provide the corresponding software libraries free of charge. Furthermore, the open-source code samples take advantage of the popular Arduino IDE with its excellent programming capabilities.

LIN Bus
The demand for a second serial network emerged as the technologies and the facilities implemented in modern cars grew, while the CAN Bus was too expensive to implement for every component in the car. Copperhill Technologies provides several LIN Bus breakout boards for prototyping, including isolated LIN and LIN Bus Slave boards for functionality testing. More Information... |
We at Copperhill Technologies keep a focus on CAN Bus (Controller Area Network) technologies and higher-layer protocols, such as OBD-II, SAE J1939, and CANopen. 
When it comes to quick prototyping, without the requirement of an operating system, we rely primarily on the popular Arduino platform, specifically the Arduino Due. The Arduino Due is the first Arduino board based on a 32-bit ARM core microcontroller. With 54 digital input/output pins, 12 analog inputs, it is the perfect board for robust larger scale Arduino projects.
We offer a great variety of CAN Bus boards for the Raspberry Pi (HATs), Arduino (Shields), and BeagleBone (Capes) but also breakout boards for embedded systems. Also included are programmable systems for quick prototyping, such as an Arduino-based USB to Dual-CAN gateway, a CANopen breakout board, CAN Bus to UART converter, and more. All systems are supported by detailed documentation and a great selection of programming samples. 
The CAN FD protocol has taken application software closer to "real time" through the minimization of delays between instruction and transfer of data (latency) and higher bandwidth. CAN FD provides more storage capacity in the CAN Bus data frame. Copperhill Technologies offers a large selection of CAN FD boards for various prototyping needs, may it be the Raspberry Pi or other embedded systems. In addition, we offer complete CAN FD development boards based on the Teensy (Arduino-compatible) ARM processor.
We have developed our own SAE J1939 protocol stack, and, in the best sense of rapid prototyping, we used the Arduino platform (UNO, Mega 2560, DUE) as a test hardware. Since then, we ported the code to the NXP LPC17xx ARM Cortex processor family, which we use as the base of our own embedded SAE J1939 systems such as an
LIN (Local Interconnect Network) is a serial network protocol used for communication between components in vehicles. Featured Products
