About the CARVanta Sentinel v2 PCB
CARVanta Sentinel v2 is an open source ESP32 PCB design by dhruv1859, published on GitHub under the Apache-2.0 license. It is a 6-layer board measuring 100 × 100 mm, with 86 components from 30 distinct parts.
Its main chip is the ESP32-S3-WROOM-1, from the ESP32 family. Other key parts include the BQ24075RGT, AMS1117-3.3, TCA9548AMRGER, LMP91000 and ADS1256. By type, the board carries 40 capacitors, 16 resistors, 14 ICs, 7 connectors, 4 diodes and 2 switches.
It belongs with the rf & radio, iot & wireless and power & battery designs in this gallery.
From the project
This board monitors 4 antigens simultaneously (CD19, CD22, BCMA, GPRC5D), meaning 4 independent electrochemical channels that MUST be electrically isolated from each other and from the digital noise of the ESP32 + WiFi radio.
