M5Stack Capsule Kit v1.1- A Battery-powered ESP32-S3 IoT controller with IMU sensor, MEMS microphone, and IR transmitter

M5Stack Capsule v1.1 is a Stamp-S3A-based IoT controller with a microSD card slot, several sensors (6-axis IMU, microphone), an IR transmitter, a built-in 250 mAh battery, a few buttons, a buzzer, an RTC, and expansion capabilities through GPIO headers and a Grove connector. It’s an upgrade to the earlier Capsule based on the Stamp-S3 module. The new version still features an ESP32-S3 WiFi and Bluetooth microcontroller, 8MB flash, a USB-C port, and a few GPIOs, but benefits from the Stamp-S3A improvements, including an optimized antenna design and lower power consumption. We never had a look at the Capsule before, so let’s do it now. M5Stack Capsule v1.1 specifications: M5Stack Stamp-S3A module WiSoC – Espressif Systems ESP32-S3FN8 CPU Dual-core 32-bit Xtensa LX7 microcontroller with AI vector instructions up to 240MHz RISC-V ULP co-processor Memory – 512KB SRAM Storage – 8MB flash Wireless – 2.4GHz WiFi 4 (802.11b/g/n), Bluetooth 5.0 LE + […]

Flipper One – A Rockchip RK3576-powered portable Arm Linux computer and networking multi-tool

Flipper Devices has officially introduced the Flipper One open-source hardware portable Arm Linux platform and networking and Edge AI multi-tool powered by a Rockchip RK3576 octa-core Arm Cortex-A72/A53 SoC, and featuring a Raspberry Pi RP2350 for low-level control. You may think of it as a successor to the popular STM32-based Flipper Zero hardware and wireless hacking tool, but the company stresses that the Flipper One is NOT a replacement for the Flipper Zero. It is a different product with mainline Linux kernel support, no binary blobs (probably not 100% true), and open-source drivers, and operating at a different level of the networking and wireless stacks with dual Gigabit Ethernet, Wi-Fi 6E, and optional 5G or 4G LTE modem. Flipper One specifications: SoC – Rockchip RK3576 CPU 4x Cortex-A72 cores @ 2.2GHz, 4x Cortex-A53 cores @ 1.8GHz Arm Cortex-M0 MCU at 400MHz GPU – ARM Mali-G52 MC3 GPU with support for […]

ESP32-S3 PowerFeather V2 board gains support for LiFePO4/LFP batteries

ESP32-S3 PowerFeather V2 LiFePO4 battery support

The ESP32-S3 PowerFeather V2 board is an ESP32-S3 WiFi and BLE IoT board with an Adafruit Feather form factor that supports LiFePO4/LFP batteries, as well as Li-Ion or LiPo batteries, and up to 18V DC input for solar panel connection. As one could have guessed, it’s an update to the ESP32-S3 PowerFeather board introduced in 2024 with support for solar panel input, Li-Ion, and LiPo batteries. The V2 design is virtually identical, except it features an Analog Devices MAX17260 fuel gauge and a TPS631013 buck-boost regulator that keeps 3.3 V stable to add support for LiFePO4 batteries. Lithium Iron Phosphate batteries are said to be safer and longer-lasting than Li-ion or LiPo batteries, albeit at the cost of lower energy density. ESP32-S3 PowerFeather V2 specifications: ESP32-S3-WROOM-1-N8R2 SoC – ESP32-S3 CPU – Dual-core Tensilica LX7 up to 240 MHz Memory – 512KB SRAM, 16 KB RTC SRAM Wireless – 2.4 GHz […]

PENOX WristBuds – A Bluetooth 6.0 smartwatch with integrated TWS earbuds (Crowdfunding)

WristBuds 2 in 1 Smartwatch with ENC Earbuds

PENOX WristBuds is a 2-in-1 rugged Bluetooth 6.0 smartwatch with integrated TWS earbuds, eliminating the need for a separate charging case. Designed for outdoor enthusiasts and the “zero-clutter mobility” market. The watch is built around a Bluetrum AB5681G RISC-V smartwatch MCU managing both the smartwatch interface and audio synchronization. The device sports a large 2.1-inch IPS display with a 320×390 resolution and is housed in a CNC-machined zinc alloy body. But what’s interesting about this is its mechanical, spring-loaded “Pop & Snap” design that houses the TWS earbuds inside the watch, and eliminates the need for a separate charging case. PENOX WristBuds specifications: MCU – Bluetooth AB5681G CPU – 32-bit RISC-V CPU @ up to 140 MHz Memory – TBC (not mentioned at all in the MCU datasheet) Storage – 128Mbit integrated NOR Flash Display & Graphics – SPI/QSPI display engine with HW acceleration (DMA, rotation, scaling, blending) Audio – […]

Mind xPlay display and keyboard review using Khadas Mind and Mind 2 mini PCs

Khadas xPlay connected to Crowview USB C display

In this review, I’ll report my experience with the Khadas Mind xPlay display and keyboard using the Mind and Mind 2 mini PCs, as well as a CHUWI CoreBook Air Plus 16 laptop to test it as a standard external display. Using Mind xPlay with the Mind 2 mini PC I received the Mind xPlay with the Mind 2 Meteor Lake mini PC, and I already showed how to connect it and get started in the first part of the review. So I’ll continue the review with it initially. I used the EIZO monitor test website to evaluate the display panel itself. I went through all 13 tests, including dead pixel and gradients tests. The pattern above looks fine too, so I compare the Mind xPlay monitor to the 16-inch display of the ASUS Vivobook 16 to find differences. Both were set to maximum brightness. The xPlay delivers noticeably more […]

Pi Slate – A Raspberry Pi 5 handheld Linux cyberdeck with a 5-inch 1280×720 touchscreen display

We previously wrote about Carbon’s CyberT, a Blackberry-style Raspberry Pi CM4 handheld Linux cyberdeck designed for Kali Linux and penetration testing. The company, now operating under the CyberArch/Carbon Computers brand, has introduced the Pi Slate, a more powerful handheld cyberdeck designed for portable computing and security-focused applications. Built around the Raspberry Pi 5, the Pi Slate integrates a 5-inch 1280×720 touchscreen, a backlit RGB keyboard with an integrated cursor, and a 10,000 mAh battery for 3–5 hours of portable use in a compact enclosure. It supports modular expansion for HATs such as LoRa, SDR, AI accelerators, and M.2 storage, and includes cooling support, antenna mounts, and an optional modular back with a kickstand. It targets penetration testers, IT professionals, and field technicians needing a compact, preconfigured system for cybersecurity and field work. Pi Slate specifications: SBC – Raspberry Pi 5 with 2GB, 4GB, 8GB, or 16GB LPDDR4X RAM options Storage […]
