Hi Jan K., Just last week I completed a similar task successfully, so I can get started on this without any ramp-up time. 1) How many EEG channels, target sample rate/bit depth, and electrode type (dry/wet)? Do you need impedance monitoring and a driven-right-leg (DRL) reference, and what input‑referred noise floor is acceptable? 2) What are the mechanical constraints (board size/stack‑up), antenna approach (chip/PCB/pre‑certified module), and expected battery capacity/runtime? Is charging permitted while worn? Suggestion 1: Pair an EEG AFE (ADS1299‑class or similar) with an nRF52 BLE SoC; use split analog/digital planes with single‑point tie, guarded inputs, DRL, low‑noise LDOs for analog, and DC‑DC only on digital to suppress ripple. Suggestion 2: Use a pre‑certified BLE module with tuned chip antenna and OTA DFU; add a fuel gauge (MAX17048) plus ESD/TVS and input protection on electrodes for safety and reliability. Action Plan: - Phase 1: Requirements freeze, architecture, BOM shortlist (AFE, MCU/BLE, PMIC/charger, antenna). - Phase 2: Schematic, noise/power budget, test/DFM hooks. - Phase 3: 4‑layer layout, impedance control, analog partitioning, antenna keep‑out. - Phase 4: Firmware MVP (GATT, streaming, OTA) + basic test app. - Phase 5: Prototype, bring‑up, validation (noise/CMRR/throughput/battery), iterate if needed. - Phase 6: Final docs: BOM, Gerbers, pick‑place, assembly/test. Examples of low‑noise biosignal designs can be shared Best Regards, Sid

Hi, I recently designed a low-noise biosignal acquisition board with BLE streaming, where the main challenge was isolating sensitive analog front-end signals from digital/RF noise while maintaining stable wireless performance. From your description, you need a compact wireless EEG PCB with Bluetooth, battery power, and clean biosignal acquisition. The key considerations will be ultra-low-noise analog design (AFE, grounding, shielding), proper 4-layer stackup (AGND/DGND separation), RF antenna layout, and efficient power management for stable operation. My approach would be: 1. Select EEG AFE (e.g., ADS1299-class) and BLE MCU 2. Design low-noise schematic with proper filtering and protection 3. Implement 4-layer PCB with strict analog/digital separation 4. Optimize RF section and antenna clearance 5. Develop basic BLE firmware for data streaming Quick question: How many EEG channels are required, and do you have target sampling rate/resolution in mind? Best regards Mykola
