ECG/SpO2 ADC boards
This project consists in two boards for connecting analog front ends and ADC ICs for measuring SpO2, ECG and respiratory rate. The boards arrived very quickly, manufacturing was also within the expect...
Power IC breakout
With this board we tested some power ICs, unfortunately they did not perform well. Thanks to PCBway however we did not spend too much to test this solution as this was only 5$.
Temperature sensor breakout
This is a breakout board to obtain an i2c based probe like temperature sensor with 0.1°C accuracy. The widely available waterproof sensors on the market do not achieve this accuracy so we developed th...
AFE4490 SMD
For this order we got a prototype for our AFE4490 board with SMD components. This provides SpO2 readings with both wired SPI and wireless wi-fi interfaces for our project. The quality seems pretty goo...
JLAB amplification board
I've visually inspected some boards and they seem pristine without defects. The HASL leveling is not as good as ENIG but it is cheap and works well for my applications, plus PCBWay sent more items tha...
ECG filter
This board we developed to test several combinations of anti-alias RC filters both differential and single ended.
Stencil for AFE4490 board
This is the stencil for the AFE4490 board, we used 1.2mm thichness however it seems to be too little for the QFN package, on the other hand it is too much for some 0805 components, be careful about sh...
