I need a breakout board based on SIM5320 for experimenting web server http requests. I've found the board shown above in adafruit library and thought of using it as reference and slim it down to the requirements by removing unwanted circuitry.As marked in the pic, all the circuits marked with cross are not needed. And the component to which the arrow mark is pointing is the one I need to know how to create one similar to it in Altium or Eagle cad. I see it says GPS BIAS with 33nH inductor and not sure what those half rounded pads with pin nos connected to or the component type used.
Also for this board I'll be using 9V external voltage source along with LDO circuit as mentioned in the SIM5320 Datasheet.I've calculated the required resistances to be used to get the desired LDO output voltage. Also I will be be using all 3 protocols (UART, SPI, I2C) and for these I will be putting separated headers so that I can use the desired ones when needed.I hope that should be enough to RPi to take care of SIM5320 . Need some one to check my approach and let me know If there are any other changes to be done in the circuitry.
