Product Overview
BMD101 is NeuroSky’s 3rd‑generation ultra‑low‑power bio‑signal SoC AFE. It acquires micro‑volt ECG, EEG and EMG biopotential signals, integrating 16‑bit ADC, hardware filters and on‑chip RC oscillator. Raw waveform and heart‑rate data are transmitted over UART 57600 baud. Ideal for wearable health monitors, BCI and portable biometric sensing devices.
Core Advantages
Low‑Noise AFE Front‑End
High‑gain low‑noise amplifier, supports both stainless‑steel dry electrodes and Ag‑AgCl gel electrodes.
On‑Chip Hardware Filtering
Built‑in 50/60Hz notch and high‑pass filters, suppress power‑line noise and baseline drift, reducing MCU workload.
Ultra‑Low Power
Typical 0.8mA operating current, 2.7V‑3.6V supply, well‑suited for battery‑powered wearable products.
Compact SON‑8 & UART Output
Small SON‑8 SMD package, UART with TX FIFO, outputs raw biometric data to accelerate product development.

Frequently Asked Questions
Q1: What biological signals can BMD101 measure?
A: BMD101 captures micro‑volt biopotential signals: ECG, EEG and EMG.
Q2: Does BMD101 support dry electrodes?
A: Yes. High input impedance (>10GΩ) supports stainless‑steel dry electrodes, also compatible with standard Ag‑AgCl gel electrodes.
Q3: How does BMD101 output data to host MCU?
A: Raw waveform and status data output via fixed 57600 baud UART interface, works with MCU, Bluetooth or WiFi modules.
Q4: Are there alternative parts for BMD101?
A: Function‑similar options: AD8232, ADS1292R. None are pin‑to‑pin compatible. PCB schematic and firmware must be reworked for replacement.
Q5: What is BMD101 package? Are there other suffix versions?
A: Genuine BMD101 uses SON‑8 package, no official alternate package variants. Chips marked QFN‑16 are likely counterfeit.
Q6: Can BMD101 run on 5V supply?
A: Operating range 2.7V‑3.6V, typical 3.3V with internal 1.2V regulator. 5V input will destroy the chip.
Q7: Is external crystal required for BMD101?
A: No, built‑in RC oscillator, no external crystal needed to reduce BOM cost.
Q8: Is BMD101 medically certified?
A: This is industrial‑grade component without medical certification. End‑medical equipment needs independent full‑product certification.
Q9: Where can I get datasheet and volume quotation?
A: Submit quick inquiry for datasheet, hardware guide, samples and bulk pricing.
