Hardware Architecture
The physical Zenso frame blends precision Japanese electronic engineering with ultra-low-power embedded circuitry.
Seeed Studio XIAO ESP32-S3
Section titled “Seeed Studio XIAO ESP32-S3”The frame core is powered by the compact Seeed Studio XIAO ESP32-S3 module, featuring a dual-core Xtensa 32-bit LX7 processor running at 240 MHz, integrated 2.4 GHz Wi-Fi (802.11 b/g/n), Bluetooth 5.0 LE, 8 MB PSRAM, and 8 MB SPI Flash.
Hardware Power Gating (< 15 µA Sleep)
Section titled “Hardware Power Gating (< 15 µA Sleep)”To deliver months of battery life, the custom EE04 carrier board incorporates a high-side MOSFET power gating circuit. Between refresh intervals, power to the display controller and external peripherals is physically severed, dropping overall standby current draw below 15 µA.
50-Pin FPC Connector & Battery Circuit
Section titled “50-Pin FPC Connector & Battery Circuit”The carrier board features a standard 50-pin 0.5mm pitch FPC receptacle compatible with Waveshare and Good Display raw panels, paired with an onboard TP4056/BQ-series Li-Ion charging controller and voltage divider connected to ADC GPIO for battery monitoring.
