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

M5Stack Stamp-S3A Capsule v1.1 module

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 + […]

NanoPi M6V2 RK3588S SBC gains support for dual analog microphone input

NanoPi M6V2

FriendlyELEC’s NanoPi M6V2 is an update to the NanoPi M6 Rockchip RK3588S SBC, whose main change is a 4-pin connector for dual analog microphone input. The RAM is also now fixed to 8GB (no more 4GB, 16GB, or 32GB options), some buttons have changed, and the company has stopped offering an enclosure with a built-in 3.5-inch display. The rest of the specifications remain the same, with LPDDR5 memory, support for microSD, eMMC flash, or NVMe storage, HDMI 2.1 and MIPI DSI display interfaces, MIPI CSI camera inputs, Gigabit Ethernet and optional M.2 WiFi/Bluetooth connectivity, a few USB ports, and a 30-pin GPIO header. NanoPi M6V2 specifications: SoC – Rockchip RK3588S CPU – Octa-core processor with 4x Cortex-A76 cores @ up to 2.4 GHz, 4x Cortex-A55 cores @ up to 1.8 GHz GPU – Arm Mali-G610 MP4 GPU compatible with OpenGL ES 3.2, OpenCL 2.2, and Vulkan 1.2 APIs VPU – […]
