JColvin Posted October 24, 2018 Share Posted October 24, 2018 Hi @zwilcox, I have asked one of my colleagues for the specific datasheet or at least the appropriate values for the shunt resistor. Thank you, JColvin Link to comment Share on other sites More sharing options...
JColvin Posted October 24, 2018 Share Posted October 24, 2018 Hi @zwilcox, I heard back that we used a Yageo RC0402JR-070RL as the shunt resistor. One of our hardware engineers did mention though that the maximum current draw for the Pmod USBUART is 50 mA, so the voltage drop (including the shorting block) will likely be about 5mV. Let me know if you have any questions about this. Thank you, JColvin Link to comment Share on other sites More sharing options...
