  "textContent": "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 + [...]\n\nThe post M5Stack Capsule Kit v1.1- A Battery-powered ESP32-S3 IoT controller with IMU sensor, MEMS microphone, and IR transmitter appeared first on CNX Software - Embedded Systems News.",
