ITBPMM INTERFACEIn the left edge of the top PCB side, bottom to top:1. RX[TXD] - modem TX - output 2. TX[RXD] - modem RX - input 3. RST - MODEM RESET - input, active HIGH* 4. ENA - ENABLE MODEM POWER - input, active HIGH** 5. Vusb - POWER PIN - output +5V (USB +5V) 6. Vin - POWER PIN - input +5V for LiPol charger only 7. Vcc - POWER PIN - input/output +4V** 8. GND - POWER and DIGITAL GROUND 9. RI - RING INDICATOR - output 10. STATUS - STATUS - output * min. 250msec. pulse [HIGH level] will RESET the modem, excepting BG96 variant. RST pin have alternate functionality, as POWER ON / POWER OFF / exit PSM mode, for BG96 variants. ** HIGH level will enable modem power. All u-GSM variants, excepting BG96, will be waked [POWERED ON]. ** LOW level disconnects the modem power. All u-GSM variants will shutdown. *&** To wake BG96 variant, keep ENA pin to HIGH level and then apply 250ms HIGH level pulse to RST pin. Raspberry PI embedded interfaceIn the PCB top side left hand, from left to right:RPI02 - Vin <--> RPI 5V* RPI04 - Vin <--> RPI 5V* RPI06 - GND <--> RPI GND RPI08 - TX[RXD] <--> RPI SERIAL TX** RPI10 - RX[TXD] <--> RPI SERIAL RX** RPI12 - STS <--> RPI GPIO18 RPI16 - ENA <--> RPI GPIO23 RPI16 - RST <--> RPI GPIO24 * Read about sjp7 functionality bellow. ** Read about sjp5 and sjp6 functionality bellow. BeagleBone Black embedded interfaceIn the PCB top side right hand, from right to left:P9.01 - GND <--> BBB GND P9.02 - GND <--> BBB GND P9.05 - Vin <--> VDD 5V* *** P9.06 - Vin <--> VDD 5V* *** P9.11 - RX[TXD] <--> GPIO_30[UART4_RXD]** P9.12 - RST <--> GPIO_60 P9.13 - TX[RXD] <--> GPIO_31[UART4_TXD]** P9.15 - ENA <--> GPIO_50 P9.16 - STS <--> GPIO_51 * Read about sjp7 functionality bellow. ** Read about sjp5 and sjp6 functionality bellow. LEDs, switches and additional interfacesPCB top edge, left to right:1. RST switch - RESET function for all versions, excepting BG96. POWER ON / POWER OFF / exit PSM mode for BG96 version 2. GREEN LED - network status LED 3. YELLOW LED - power status LED 4. GNSS u.FL connector [only for BG96 version] 5. LiPO / LiION battery connector [GND, +] Left PCB side, inside PCB, from top to bottom: 1. GND - super-capacitor soldering PAD, negative pole 2&3. Vbat - super-capacitor soldering PADs, positive pole PCB bottom edge, from left to right: 1. USB connector type miniB 2. USB soldering PADS [GND, D-, D+, Vusb] Right PCB edge: 1. nano SIM socket connector Solder jumperssjp1* - RESERVED - default circuit closed.sjp2 - Active GNSS antenna powering - default, the active GNDD antenna power is enabled [circuit closed]. Relevant only for BG96 variant. sjp3 - disable LEDs powering - default, LEDs power is enabled [circuit closed]. STS [STATUS] signal is disabled if LEDs power is disabled. sjp4 - bypass modem power separation - default disabled [circuit open]. If enabled, ENA input will lose its role. sjp5 and sjp6 - connect modem UART to RPI and BBB embedded interfaces - default connected [circuits closed]. If disconnect, RPI/BBB RX and TX GPIOs will be released. You may like to use this option if modem is connected to RPI/BBB via USB. sjp7* - connect Vin to BBB/RPI 5V - default connected - u-GSM us as power supply 5V from RPI / BBB [circuit closed]. If disconnect, u-GSM may be powered independent. BBB voltage selector* - use BBB Vdd 5V / SYS 5V as power source - default Vdd 5V is used as power source. Relevant if u-GSM is connected with BBB. sjp5, sjp6, sjp7 and BBB voltage selector are relevant only if u-GSM is connected to BBB/RPI via embedded interfaces. * consult u-GSM block schema. External SIM CARD port, antenna connectorExternal SIM card interface 1. SIM VDD 2. SIM DATA 3. SIM RESET 4. SIM GND 5. SIM CLOCK - if not used, leave them not connected - if used, in order to avoid interferences, keep the wires as short as possible and take in to account the routing. GSM side antenna connector u-GSM shield may be ordered with u.FL connector or with SMA F connector. Check here: u-GSM part numbers. PCB breaking linesIf required the u-GSM PCB may be trimmed across the breaking lines. We recommend to you to trim the u-GSM PCB only if you intend to fit your Raspberry PI & u-GSM shield assembly into one RPI case.Guidelines here. |
