Analog Devices Inc./Maxim Integrated MAX30110ACCEVKIT#

Overview

MAX30110ACCEVKIT# from Maxim Integrated is an evaluation kit for the MAX30110 optical pulse oximetry and heart rate analog front-end IC. It enables rapid prototyping of wrist-worn and in-ear wearable health monitors, featuring integrated 19-bit optical ADC, dual 8-bit LED current DACs (up to 200mA), ambient light cancellation up to 200μA, and SPI interface with 32-sample FIFO.

For engineers reviewing the MAX30110ACCEVKIT# datasheet, MAX30110ACCEVKIT# pinout, MAX30110ACCEVKIT# application, or MAX30110ACCEVKIT# equivalent, this kit provides validated hardware reference design, preconfigured firmware examples, and direct access to the MAX30110's full feature set-including dynamic power-down mode (25μA typical at 25sps), programmable integration times (52–417μs), and transmissive/reflective SpO₂/HR measurement support.

Technical Context

The MAX30110ACCEVKIT# implements the complete signal chain of the MAX30110 AFE: two independent LED drivers with four selectable current ranges (50/100/150/200mA), a 19-bit sigma-delta ADC with 25pA-RMS input-referred noise, and built-in front- and back-end ambient light cancellation. It supports both reflective and transmissive optical configurations using external photodiodes and LEDs.

This evaluation kit exposes all 24-bump WLP pins of the MAX30110 via accessible test points and headers, including dedicated VLED (3.1–5.25V), VDD_ANA/VDD_DIG (1.8V), PD_IN/PD_GND, LED1_DRV/LED2_DRV, and SPI signals (SDO/SDI/SCLK/CSB/INT/FCLK). It operates across –40°C to +85°C and integrates decoupling capacitors per Maxim's layout guidelines.

FAQ

What is the primary function of the MAX30110ACCEVKIT#?

The MAX30110ACCEVKIT# is an evaluation kit for the MAX30110 optical analog front-end IC. It provides a fully assembled, tested PCB with the MAX30110 WLP device, supporting immediate validation of pulse oximetry and heart rate detection algorithms. The kit includes onboard voltage regulation, LED/photodiode interface points, and USB-to-SPI bridge for host communication-enabling rapid firmware development without custom hardware design.

Does the MAX30110ACCEVKIT# include firmware or software tools?

Yes, the MAX30110ACCEVKIT# ships with Maxim's official evaluation software suite, including GUI-based configuration tools, real-time data streaming, and example firmware for Arduino and ARM Cortex-M platforms. These resources directly interface with the MAX30110's registers-allowing users to configure sample rates (20–3200sps), LED current (50–200mA), integration time (52–417μs), FIFO settings, and ambient cancellation parameters without low-level driver development.

Can the MAX30110ACCEVKIT# be used for both reflective and transmissive optical sensing?

Yes, the MAX30110ACCEVKIT# supports both configurations. Its board layout provides separate, labeled pads for LED anode/cathode connections and photodiode cathode/anode routing (PD_IN/PD_GND), enabling flexible placement of external emitters and detectors. The MAX30110 IC itself natively supports either topology through register-controlled timing and channel selection-verified in the kit's included reference designs for wrist-worn (reflective) and earbud (transmissive) use cases.

What power supplies are required to operate the MAX30110ACCEVKIT#?

The MAX30110ACCEVKIT# operates from a single 5V USB input, which it internally regulates to 1.8V for the MAX30110's digital and analog cores (VDD_DIG/VDD_ANA) and to 3.3V for the LED driver supply (VLED). No external power sources are needed-the kit includes all necessary LDOs, decoupling capacitors, and ESD protection aligned with Maxim's recommended layout for production designs.

Is the MAX30110ACCEVKIT# compatible with standard microcontroller development environments?

Yes, the MAX30110ACCEVKIT# features a standard 10-pin 2×5 header compatible with common ARM SWD/JTAG debuggers and includes breakout pads for SPI signals (SCLK, SDI, SDO, CSB, INT, FCLK). Example code and drivers are provided for STM32, nRF52, and ESP32 platforms, and the SPI interface complies with Microwire/QSPI timing-ensuring seamless integration into existing embedded toolchains without protocol translation or hardware adaptation.
