Product details

Overview

SI7013EVB-UDP-M3L1 from Silicon Laboratories is an evaluation kit comprising a Si7013 digital humidity and temperature sensor mounted on a port header card (Si7013EB-UDP) and a SiM3L1xx 32-bit Precision32™ MCU development card with multiplexed LCD (SiM3L1xxLCD-B-DK), configured as a battery-operated data logger. It supports I²C communication, stores up to 8192 samples in flash memory, and operates at default 2-minute sampling intervals.

For engineers reviewing the SI7013EVB-UDP-M3L1 datasheet, SI7013EVB-UDP-M3L1 pinout, SI7013EVB-UDP-M3L1 application, or SI7013EVB-UDP-M3L1 equivalent, this kit delivers validated firmware for low-power environmental monitoring, PC-based configuration via CP2103 UART bridge, and hardware integration with UDP platform headers - enabling rapid prototyping of sensor-to-cloud logging systems.

Technical Context

The SI7013EVB-UDP-M3L1 integrates the Si7013 sensor (QFN24, 4×4 mm, 0.5 mm pitch) with the SiM3L1xx MCU (ARM Cortex-M3 core, ultra-low-power operation) on a standardized Unified Development Platform (UDP) interface. The Si7013 communicates over two independent I²C buses: one dedicated to the onboard sensor (SDA→P1.5, SCL→P1.6, CS→P1.7), and another routed to J2 for optional "postage stamp" evaluation boards (e.g., Si7020/Si7021).

Firmware includes dual software projects: a real-time Demo mode displaying live temperature/humidity on LCD with button-driven unit/thermistor selection, and a full Data Logger mode supporting configurable sampling (1 sec–18 hr), alarm thresholds (–40°C to +85°C), timestamping, and CSV export via PC application. Power management enables multi-day battery operation using coin-cell or USB-supplied VBAT.

FAQ

What is the SI7013EVB-UDP-M3L1 used for?

The SI7013EVB-UDP-M3L1 is an evaluation kit that demonstrates and enables development of battery-powered temperature and humidity data loggers. It combines the Si7013 sensor and SiM3L1xx MCU to provide out-of-box firmware for real-time display, configurable sampling, alarm generation, and PC-based data retrieval - ideal for validating environmental sensing subsystems before custom PCB design.

Does the SI7013EVB-UDP-M3L1 include software and documentation?

Yes, the SI7013EVB-UDP-M3L1 includes a CD with complete software: pre-built Demo and Data Logger firmware images, source code (C-based), CP2103 VCP drivers, and the Si7013EVB-UDP-M3L1 User's Guide (Rev. 0.2). No compilation is required - batch files install firmware directly to the SiM3L1xx MCU card via USB Debug Adapter.

How is the Si7013 sensor interfaced in the SI7013EVB-UDP-M3L1?

In the SI7013EVB-UDP-M3L1, the Si7013-A-GM1 sensor is mounted on the Si7013EB-UDP port header card and connects to the SiM3L1xx MCU via I²C: SDA to P1.5, SCL to P1.6, and CS to P1.7. A second I²C bus is available at J2 (FH12 connector) for daisy-chaining additional Si7013, Si7020, or Si7021 "postage stamp" evaluation boards.

Can the SI7013EVB-UDP-M3L1 operate standalone without a PC?

Yes - once programmed, the SI7013EVB-UDP-M3L1 runs autonomously on battery power. The Data Logger firmware sleeps between samples to extend runtime; pressing the center joystick (U9) wakes it, and S3 starts/stops logging. The LCD displays live readings, timestamps, sample count, and alarms - no PC connection is needed during deployment.

What are the key hardware components included in the SI7013EVB-UDP-M3L1 kit?

The SI7013EVB-UDP-M3L1 kit contains two main hardware units: (1) the SiM3L1xxLCD-B-DK MCU card featuring a SiM3L1xx 32-bit ARM Cortex-M3 MCU with integrated LCD driver and CP2103 USB bridge, and (2) the Si7013EB-UDP port header card hosting the Si7013-A-GM1 sensor, thermistor interface, and dual I²C routing. Also included: USB Debug Adapter, power supply, and software CD.
