ESP32-C5 devkit offers 2.8-inch capacitive touch display, dual-band Wi-Fi 6, Bluetooth 5 LE, LiPo battery support

Last week, I wrote about the ESP32-C5-LCD-1.47 as one of the first ESP32-C5 devkits with a built-in display enabling dual-band WiFi 6 connectivity for IoT and HMI projects. However, one reader lamented the lack of touch-capable screens, at which point kwchow pointed to the ESP32-C5-Touch-LCD-2.8 model offering just that by pairing an ESP32-C5 with a 2.8-inch IPS display with capacitive touch and 320×480 resolution. The new board also features a microSD card slot, a USB-C port for power and programming, a built-in microphone and a speaker connector, a few sensors, and various I/Os connectors for expansion. Let’s have a closer look. ESP32-C5-Touch-LCD-2.8 specifications: Wireless module – Espressif Systems ESP32-C5-WROOM-1-N32R8 SoC – ESP32-C5HR8 CPU Single-core 32-bit RISC-V processor @ up to 240 MHz Low-power RISC-V core @ 40 MHz acting as the main processor for power-sensitive applications Memory – 384 KB SRAM on-chip, 8MB PSRAM Storage – 320 KB ROM Wireless […]

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 […]
