Flashchip FCM32 is yet another alternative to STM32 microcontroller

Flashchip Microelectronics FCM32 development board

Once upon a time, people tried to avoid STM32 fakes and clones, but in a world where companies are allegedly purchasing washing machines to extract a few unavailable components, people have started to look for alternatives, and last week I wrote about the Geehy APM32 family of STM32 clones. But I had never heard about Flashchip Microelectronics FCM32 microcontrollers, and they are not that easy to find in search engines, so they must be relatively new. The company appears to make both FCM32F clones and FCM32H derivatives with no direct equivalent STM32 part numbers, a higher clock frequency, and faster flash. For example, the FCMF030F4P6 will match the specifications of STMF030F4P6 as far as I can tell. The good news is that the datasheet is available in both Chinese and English. The FCM32H030C8T6 appears to be a higher performance version of STM32F030C8T8 / FCM32F030C8T8 with a 100 MHz frequency, and […]

CANBed M4 SAM E51 development board features MCP2542FD CAN transceiver

CANBed M4 development board based on Microchip SAM E51 Cortex-M4 microcontroller and MCP2542FD CAN transceiver provides a more powerful alternative to the CANBed RP2040 with a Raspberry Pi dual-core Cortex-M0+ microcontroller introduced last year. The board supports both CAN 2.0 and CAN FD with a 4-pin terminal block or a DB-9 connector, and offers expansion capabilities though two Grove connectors, and an 18-pin IO header. CANBed M4 specifications: MCU – Microchip ATSAME51G19A Arm Cortex M4 core @ up to 120 MHz with 512KB flash, 192KB RAM CAN Microchip MCP2542FD CAN transceiver with support for CAN 2.0 and CAN FD up to 2+ Mbps Input interface – DB-9 connector or terminal block 120 Ohm terminal resistor USB – 1x Micro USB port for programming Expansion I2C Grove connector UART Grove connector SPI header 18-pin I/O header with up to 12x GPIOs, UART, I2C, 4x analog inputs, 5V, and GND Misc – […]

LILYGO T-QT V1.1 – A cute little board with ESP32-S3 and a 0.85-inch color display

LILYGO must be churning out at least one new “ESP32” board every month, but I don’t think they’ve ever made one with ESP32-S3. LILYGO T-QT V1.1 board changes that and combines the dual-core WiFi 4 and Bluetooth LE 5.0 AI microcontroller with a 0.85-inch color display. The board also happens to be rather small and cute with a 33 x 18 mm form factor, offers some I/O via headers and a 4-pin connector, and can be powered via its USB Type-C port or a battery, but lacks a charging circuit. LILYGO T-QT V1.1 specifications: Wireless MCU – Espressif Systems ESP32-S3 dual-core Tensilica LX7 @ up to 240 MHz with vector instructions for AI acceleration, 512KB RAM, wireless connectivity Storage – 8MB flash Connectivity via ESP32-S3 2.4 GHz 802.11 b/g/n Wi-Fi 4 with 40 MHz bandwidth support Bluetooth Low Energy (BLE) 5.0 connectivity with long-range support, up to 2Mbps data rate.

ROCK 5B developer edition preview – Part 1: Unboxing and first boot to Debian 11

Radxa ROCK5 Model B (aka ROCK 5B) is one of the most anticipated Rockchip RK3588 single board computers due to its features set and relatively affordable price. It was first showcased in January, but it’s taking a while as the Cortex-A76/A55 SoC is a complex beast. The good news is that the public launch is getting closer as Radxa sent “developer edition” samples to developers and enthusiasts for a “debug party”. I was one of the recipients so, in this post, I’ll have a closer look at the latest revision of the board, and give it a quick try first before going into more details in the second of this preview. ROCK5 Model B unboxing I received the 16GB RAM version which should be the same for all board part of the “developer edition batch. Developers are invited to submit reports to Radxa forums, and since those are public, anybody […]

STEPFPGA FPGA board is programmable with a Web IDE (Crowdfunding)

STEPFPGA MXO2Core miniature FPGA development board is based on Lattice MXO2-4000 FPGA, and designed for education with an easy-to-use Web IDE, instead of the more traditional tools that can be frustrating to use, and detailed tutorials. The board also comes with a 2-digit segment display, some LEDs, push buttons, and a 4-way DIP switch, as well as two rows of twenty pins for I/O expansion, and a USB Type-C port used for power, programming, or mass storage. STEPFPGA MXO2Core specifications: FPGA – Lattice Semi MachXO2 X02-4000 FPGA with 4320 LUTs Display – 2-digit segment display USB – 1x USB Type-C port for power, programming (UART), and mass storage Expansion – 2x 20-pin headers with up to 36x GPIOs, SPI, I2C, 3.3V, VBUS, GND; breadboard-compatible Misc – 2x RGB LEDs, 8x red LEDs, 4-way DIP switch, 4x push buttons Power Supply – 5V via a USB port Dimensions – Small four-layer […]
