Boardoza ESP32-C6 Temperature Logger Evaluation Board
Boardoza ESP32-C6 Temperature Logger is a modular, ultra-low-power evaluation platform designed for high-precision environmental monitoring and long-term battery operation. Built around the ESP32-C6 RISC-V microcontroller, the board supports three distinct sensing configurations: a digital One-Wire interface for DS18B20 probe / internal sensor, TH09C I²C-based ambient sensor for temperature and humidity sensor, and MAX31865 high-accuracy SPI-driven four/three/two-wire PT1000 RTD interface. To maximize efficiency, the system integrates a zero-power e-paper display and an advanced power management stage—including a high-efficiency buck-boost converter, an ultra-low quiescent current LDO, and automated USB/battery load sharing—allowing it to maintain critical visibility while spending most of its operational life in a deep-sleep state.
Key Features
- Supports Wi-Fi 6, Zigbee, and Thread protocols for modern IoT integration.
- Single PCB design supports three models with distinct sensors:
- DS18B20 digital One-Wire sensor for external probe / internal sensor.
- TH09C Ambient Temperature and Humidity via I²C
- MAX31865 high-precision RTD logging with a PT1000 platinum resistance temperature detector.
- Drives a 24-pin FPC e-paper display that consumes no energy during deep sleep condition.
- Integrated LM66200 load switch for switching between USB-C and 4x AA Ni-MH battery power.
- Built-in battery voltage sampling with MOSFET controlled resistor dividers to eliminate leakage current during deep sleep.
- Designed to maximize battery life by spending most cycles in a low-power dormant state.
