Juy-108

If you want, I can convert this into a Jira-ready ticket with acceptance criteria and subtasks.

In JUY-108, Mikami's performance is characterized by the "innocent-yet-expressive" aesthetic that became her trademark.

| Feature | Specification | |---------|----------------| | | ARM Cortex‑M4 @ 80 MHz (with DSP extensions) | | Memory | 256 KB Flash, 64 KB SRAM | | Sensors | • Temperature (‑40 °C → +125 °C, ±0.2 °C) • Humidity (0 % → 100 % RH, ±2 % RH) • 3‑axis Accelerometer (±16 g, 12‑bit) • Ambient Light (0 → 100 klx) | | Connectivity | BLE 5.2 (2 Mbps PHY), optional UART/SPI/I²C pins | | Power | 1.8 V – 3.6 V operation; < 2 µA standby, < 0.5 mA active (typical) | | Security | Hardware‑rooted secure boot, AES‑256 encryption engine | | Package | RoHS‑compliant, conformal‑coated PCB (IP65 rated) | | Development | SDK with FreeRTOS, Zephyr, and Arduino‑compatible libraries; pre‑compiled example firmware (sensor logger, BLE beacon, motion‑trigger) |

For the next several Earth days, Juy‑108 drifted in the gentle currents, cataloguing microscopic life, measuring temperature gradients, and occasionally gliding past the towering coral forest. Its data revealed a self‑sustaining ecosystem built on chemosynthesis, not photosynthesis—life thriving on the planet’s abundant hydrogen sulfide.
