Hello. I have got a few questions about BLUENRG-MSCSP. Could you help me?
1. What par of an inductor you recommend ( Power management strategy using step-down DC-DC converter )? What par of a capacitor you recommend for filter of tep-down DC-DC converter for better stability? I will benefit in energy consumption by step-down DC-DC converter in practice?
2 I base my design on the board STEVAL-STLCS02V1. On this PCB there are many different par of a capacitorts. I want to replace 100nF ->150nF, 1uF-> 2,2uF for part optimisation. Doesn't action influence for stability or other things?
3 On the board STEVAL-STLCS02V1 the circuit "TEST1" goes to the microcontroller STM32F476. What is a signal TEST1? Can I pull-down to GND TEST1 ?
4 BLUENRG-MSCSP has got the Low speed ring oscillator (LSROSC) . If I don't use Low speed crystal oscillator (LSXOSC and exteranal 32.768rHz) I will have problems whit energy consumption or other things ?
