OpenMV CAM RT1062 camera for machine vision is programmable with MicroPython

OpenMV CAM RT1062

Following the success of the OpenMV Cam H7 and the original OpenMV VGA Camera, OpenMV recently launched the OpenMV CAM RT1062 powered by NXP’s RT1060 processor. This new camera module integrates a range of features, including a high-speed USB-C (480Mbps) interface, an accelerometer, and a LiPo connector for portability. Similar to its predecessor, this camera module also features a removable camera system, and it is built around the OV5640 image sensor which is more powerful in terms of resolution and versatility. However, the previous Omnivision OV7725 sensor, used in the OpenMV Cam H7 has a far superior frame rate and low-light performance. OpenMV provides a Generic Python Interface Library for USB and WiFi Comms and an Arduino Interface Library for I2C, SPI, CAN, and UART Comms which can be used to interface your OpenMV Cam to other systems. To program the board, you can use MicroPython 3 with OpenMV IDE, […]

Tiny Raspberry Pi RP2040 module connects to USB-C + buttons board via FPC connector

Raspberry Pi RP2040 module with FPC USB-C board

Waveshare RP2040-Tiny is another tiny Raspberry Pi RP2040 module that joins others like Pimoroni Tiny 2040, DFRobot Beetle RP2020, or Solder Party RP2040 Stamp, but with a twist as the solderable module features an FPC connector in order to optionally connect a separate board with a USB-C port as well as Boot and Reset buttons. This design enables the convenience of having a USB-C port for power and programming, plus the Reset and Boot buttons during firmware development, and developers can only keep the tiny and ultrathin module when integrating it into a project or product. Alternatively, there may be designs that benefit from having the USB-C port located further away from the main module with all I/Os, and it can also facilitate troubleshooting when the product is already integrated into a product. Waveshare RP2040-Tiny specifications: MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ up to 133Mhz with 264kB […]

Giveaway Week 2023 – Elecrow ESP32 Terminal with a 3.5-inch touchscreen display and OV2640 camera

Elecrow ESP32 Terminal giveaway

If I remember correctly, Elecrow sent me an end-of-year gift with a notebook (paper style), a pen, and a 3.5-inch ESP32 terminal. I had completely forgotten about it, and while wondering what I would give for Giveaway Week 2023, and looking around in drawers and on shelves, I found an “ESP32 Terminal” package, and I was like “What the F is that and where is it coming from?”. Long story short, the 6th prize of this year’s giveaway week is Elecrow’s ESP32 Terminal with a 3.5-inch touchscreen display that also comes with a front-facing OV2640 camera and six Crowtail connectors for expansion plus a LiPo battery connector. Elecrow ESP32 terminal specifications: Wireless module – ESP32-S3 2.4 GHz Wi-Fi and Bluetooth 5 (LE) module with 16MB flash and 8MB PSRAM Storage – MicroSD card slot Display – 3.5-inch TFT LCD display with 480×320 resolution (ILI9488 driver), capacitive touchscreen Camera – 2MP […]
