ESP32 Project: USB to Bluetooth Gateway
The ESP32 processor allows the integration of Wi-Fi, Bluetooth, and Bluetooth LE (BLE) for a wide range of IoT (Internet of Things) applications. Using Wi-Fi ensures connectivity within a large radius. At the same time, Bluetooth allows the user to easily detect (with low-energy beacons) a module and connect it to an Android/iOS smartphone or [...]
ESP32 Based CAN Bus, SAE J1939 and NMEA 2000 to Bluetooth Gateway
The following is a follow-up on our post Controller Area Network (CAN), SAE J1939, NMEA 2000 Wireless Module for IoT and ELD Applications. The CAN Bus, SAE J1939 and NMEA 2000 to Bluetooth Gateway is the first product of a new series of wireless gateways for IoT (Internet of Things), ELD (Electronic Logging Devices), and other applications. At the [...]
Controller Area Network (CAN), SAE J1939, NMEA 2000 Wireless Module for IoT and ELD Applications
Due to the global shortage of electronic components, we at Copperhill Technologies began rethinking our strategy regarding new developments. Luckily, that change turned out to be a blessing in disguise because the transition from NXP LPC to the ESP32 processor opened the door to more industrial and automotive applications, especially those involving wireless transmissions for [...]
Raspberry Pi Compute Module With CAN FD for Automation and IoT Applications
Kontron announced the release of their Pi-Tron CM4 computer with Linux OS, which utilizes the fourth-generation Raspberry Pi compute module with the 1,5-GHz, 64-bit Broadcom BCM2711 chip and four Arm Cortex-A72 processors. The computer’s steel housing allows for universal use, e.g., for automation and IoT (Internet of Things) applications. Depending on the variant, it provides a 1-GiB, 2-GB, [...]

Arduino Portenta H7 - Dual-Core STM32 Processor Board with Two CAN FD Ports and Support for Arduino IoT Cloud
The Portenta H7's central processor is represented by the dual-core STM32H747, including a Cortex M7 at 480 MHz and a Cortex M4 at 240 MHz. The two cores intercommunicate through a Remote Procedure Call mechanism that seamlessly enables calling functions on the other processor. Both processors share on-chip peripherals and can run Arduino Sketches on the Arm [...]
CAN Bus Development with ESP32-WROOM32 Development Board
This post will demonstrate how to add a CAN Bus port to the ESP32-WROOM32 development board, i.e., regarding hardware and software. Download this post as PDF... As a matter of fact, we already offer a hardware utilizing the ESP32 processor and an onboard CAN Bus transceiver as shown in the image to the left. The ESP32 WiFi, Bluetooth [...]
Wireless IoT Project Development with the ESP32
The ESP32 represents a low-cost, low-power System-on-Chip (SoC) microcontroller with integrated Wi-Fi and dual-mode Bluetooth. The ESP32 series utilizes either a Tensilica Xtensa LX6 microprocessor in dual-core and single-core variations, Xtensa LX7 dual-core microprocessor, or a single-core RISC-V microprocessor and includes built-in antenna switches, RF balun, power amplifier, low-noise receive amplifier, filters, and power management [...]
ESP32 Project: CAN Bus, SAE J1939, NMEA2000 Converter With IoT Functionality
It was just a few weeks ago that I received some bad news. Due to the worldwide shortage of electronic components, the NXP LPC1754 processor we use for our SAE J1939 ECU Simulator with USB Port will not be available for several months, maybe even well into 2022. Consequently, it was time to rethink the design, and [...]
