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
Dual-core 32-bit Xtensa LX7 microcontroller with AI vector instructions up to 240MHz
RISC-V ULP co-processor
