UniHiker review – A Linux-based STEM education platform with IoT and AI support, Micro:bit edge connector

DFRobot’s UniHiker is a STEM educational platform that was originally launched in China, but now UniHiker is now available worldwide through the DFRobot shop. The company has sent us a UniHiker sample for review, so let’s unpack the kit and learn how to use the UniHiker platform. The main component of the kit is the Linux-powered UniHiker board which features a 2.8-inch resistive touchscreen display and a BBC Micro:bit edge connector, so we can use expansion boards for the Micro:bit board. Let’s start unboxing it together. UniHiker unboxing DFRobot sent us the UniHiker platform by DHL. The package is a familiar-looking DFRobot box in orange color and comes with a plastic box to safely store the UniHiker board and accessories after use. The plastic box contains another plastic box with the board, some 3-pin and 4-pin cables for Gravity ports, and a USB Type-C cable. The UniHiker is like a […]

ESP32-S3 board features 2.8-inch display, Blackberry-like keyboard, and optional LoRaWAN connectivity

LILYGO T-Deck is a development kit with an ESP32-S3 WiFi and BLE module, a 2.8-inch display with touchscreen support, a Blackberry-like keyboard based on ESP32-S3, and optional LoRaWAN connectivity through an SX1262 LoRa module. It looks ideal for text-based messaging, but the devkit also includes two microphones and a speaker so audio communication must be possible. Other features include a MicroSD card slot, a Grove connector (UART) for expansion, and support for a LiPo battery with USB charging. LILYGO T-Deck specifications: ESP32-S3-WROOM-1 wireless module SoC – ESP32-S3FN16R8 dual-core Tensilica LX7 microcontroller @ up to 240 MHz with 2.4 GHz 802.11n WiFi 4 and Bluetooth 5.0 LE connectivity Memory – 8MB PSRAM Storage – 16MB SPI flash PCB antenna Storage – MicroSD card slot Display – 2.8-inch IPS display with 320×240 resolution; ST7789 SPI display controller Audio – Built-in speaker using MAX98357A amplifier, 2x MEMS microphones Wireless 2.4 GHz 802.11n WiFi […]

Mekotronics A58 – A 7-inch display with Rockchip RK3588 SoC and a DSLR camera mount for live streaming

7-inch RK3588 display attached to a DSLR camera

Mekotronics A58 7-inch smart display is powered by a Rockchip RK3588 SoC with up to 16GB RAM and 128GB eMMC flash, and ships with a DSLR camera mount to enable video broadcasting and live streaming on social platforms. In the past, we’ve covered several Rockchip RK3588-powered Arm mini PCs by Mekotronics such as the R58, R58X, and more recently the R58X-Pro and R58X-HDD models, but the company has now leveraged its experience with the platform by launching a 7-inch smart display that can be used for live-streaming, but as we’ll see from the specifications below can also find many other uses. Mekotronics A58 specifications: SoC – Rockchip RK3588 octa-core processor with four Cortex-A76 cores @ 2.4 GHz, four Cortex-A55 cores @ 1.8 GHz, an Arm Mali-G610 MP4 GPU, a 6TOPS NPU, 8K 10-bit decoder, 8K encoder System Memory – 4GB, 8GB, or 16GB LPDDR4X Storage 32GB, 64GB, or 128GB eMMC […]

PiccoloBASIC – A BASIC interpreter for the Raspberry Pi Pico board

PiccoloBASIC is an open-source BASIC interpreter for the Raspberry Pi Pico development board that’s based on “uBASIC: a really simple BASIC interpreter” by Adam Dunkels and relying on Arm’s LittleFS fail-safe filesystem for microcontrollers. If my memory serves me well, my first computing experience was at school using a Thomson TO7 computer that we programmed with BASIC. I don’t think the language is still used in practical applications, but we can still see some BASIC projects pop up from time to time such as a BASIC interpreter for the Arduino Zero boards. Gary Sims, owner of the Gary Explains YouTube channel, has now ported a BASIC interpreter to the Raspberry Pi Pico. The project is still work in progress, but currently implemented features include: Let, if, print, for, goto, gosub String variables (let z$=”hello”) Floating point numbers and variables (let z#=1.234) Builtin functions [zero, randint, not, time] Sleep, delay, […]
