The guidelines bellow are apliable to xyz-mIoT shield BG96 and BG95 versions! PN like: XYZMIOT209#BG96-UFL-xxxxxxx and XYZMIOT209#BG95-UFL-xxxxxxx.
Direct drive powering for xyz-mIoT shield BG96 and BG95 versions
Connect the power supply to LIPO+ and GND pads, as shown bellow.
a. power supply voltage range between 3.80V and 4.20V. Do not exceed those values! Maximum voltage drop in burst mode <200mV.
b. power supply minimum curent requirements (2G/GSM/GPRS mode) - 650-1000mA sustained, 2A pulse capable
c. power supply minimum curent requirements (LTE CATM1 / NB IoT mode) - 100mA sustained, 350mA pulse capable
d. one 1000uF low ESR capacitor, soldered to super-capacitor PADS, will increase stability in harsh radio environments. Mind the capacitor polarity!
LiPO baterry powering for xyz-mIoT shield BG96 and BG95 versions (and solar charger guidelines)
Connect the power supply to Vraw and one of GND pads in proximity and the LiPO/ LiION battery, as shown bellow.
a. use only one cell LiPO or LiION batteries!
b. do not use batteries that have leaks or seem to have any damage!
c. do not use batteries without protection circuit!
d. do not change polarities!
a. power supply voltage must be between 4.8V and 7.00V. Do not exceed those values!
b. if you want to use 5V from USB as power source, simply connect Vusb(out) to Vraw pad.
c. ONLY for LTE CATM1 or NB IoT mode [2G/GSM/GPRS mode disabled*]: instead LiPO / LiION battery, solder one 1000uF low ESR electrolytic capacitor to super-capacitor PADS. In this way the board will be stable, even in transmission mode, with 5V power applied to Vraw pad.
* this opperation is supported in xyz-mIoT BG96 classes Arduino. Read how in: xyz-mIoT BG96 NB IoT and xyz-mIoT BG96 CATM1 REST how to.
