TOBY-L4 series - System Integration ManualUBX-16024839 - R04 AppendixPage 135 of 143AppendixA Migration between TOBY-L2 and TOBY-L4A.1 OverviewTOBY-L2 and TOBY-L4 series cellular modules have the same TOBY form factor (35.6 x 24.8 mm LGA), with adifferent number of pins: as illustrated in Figure 72, TOBY-L2 modules have 152 pins, while TOBY-L4 moduleshave the same 152 pins of TOBY-L2 modules plus 96 additional pins, reaching a total number of 248 pins.Figure 72 shows that all the functions provided by the 152 pins of TOBY-L2 modules are also available on thesame pins of TOBY-L4 modules, which provide additional functions (RGMII and UART3 interfaces) on RSVD pinsof TOBY-L2 modules, intended to be left unconnected on a board designed for TOBY-L2 modules.This means that TOBY-L2 and TOBY-L4 series modules can be alternatively mounted on a single applicationboard using exactly the same copper mask, solder mask and paste mask: TOBY-L4 series modules can bemounted on any design appropriately implemented for TOBY-L2 modules, given that any additional interfaceprovided by TOBY-L4 modules will result not connected.SDIO_CMDSDIO_D0GNDVCCVCCGNDANT_DETSDASIM_IOSIM_RSTGPIO5GPIO6SDIO_D2SDIO_CLKRSVDRSVDI2S_WAI2S_CLKI2S_RXDSDIO_D1VCCGNDSCLSIM_CLKVSIMHOST_SELECT1RSVDI2S_TXDSDIO_D3V_INTVUSB_DETGNDRSVDGPIO1RSVDRSVDTXDRSVDUSB_D-HOST_SELECT0GPIO3RESET_NV_BCKPGPIO2PWR_ONRXDUSB_D+GPIO4GNDRSVDGNDGNDRSVDGNDGNDGNDGNDGNDGNDGNDGNDGNDRSVDANT2ANT1GNDRSVDGNDGNDRSVDGNDRSVDRSVDRSVDRSVDRSVDRSVDRSVDRSVDRSVDRSVDRSVDRIDSRRSVDCTSDTRDCDRSVDRSVDRTSRSVD11107542121191816151312292726242386322201714282596566697172747555575860616364474950525368707354565962485167909192 78 77 7693 10079808385868889 828487 81323130 44 45 46145 15243423937363433 403835 41999897969594106105104103102101108107124123130129128127126125136135134133132131138137144143142141140139151150149148147146114113112111110109120119118117116115122121TOBY-L2Pin 93-152: GNDSDIO_CMDSDIO_D0GNDVCCVCCGNDANT_DETSDASIM_IOSIM_RSTGPIO5GPIO6SDIO_D2SDIO_CLKRSVDRSVDI2S_WAI2S_CLKI2S_RXDSDIO_D1VCCGNDSCLSIM_CLKVSIMHOST_SELECT1RSVDI2S_TXDSDIO_D3V_INTVUSB_DETGNDRSVDGPIO1RXD3TXD3TXDETH_TX_CLKUSB_D-HOST_SELECT0GPIO3RESET_NV_BCKPGPIO2PWR_ONRXDUSB_D+GPIO4GNDRSVDGNDGNDRSVDGNDGNDGNDGNDGNDGNDGNDGNDGNDRSVDANT2ANT1GNDRSVDGNDGNDRSVDGNDETH_RX_CLKETH_RX_CTLETH_RXD1ETH_TXD0ETH_TXD1ETH_TXD3ETH_TX_CTLETH_RXD2ETH_RXD0ETH_TXD2ETH_RXD3RIDSRRSVDCTSDTRDCDRSVDRSVDRTSRSVD11RI10DSR7RSVD5V_INT4VUSB_DET2GND1RSVD21GPIO119RSVD18RSVD16TXD15CTS13DTR12DCD29ETH _TX_CLK27USB_D–26H OST_SELECT024GPIO323RESET_N8RSVD6RSVD3V_BCKP22GPIO220PWR_ON17RXD14RTS28USB_D+25GPIO49RSVD65SDIO_CMD66SDIO_D069GND71VCC72VCC74GND75ANT_DET55SDA57SIM_IO58SIM_RST60GPIO561GPIO663SDIO_D264SDIO_CLK47RSVD49RSVD50I2S_WA52I2S_CLK53I2S_RXD68SDIO_D170VCC73GND54SCL56SIM_CLK59VSIM62H OST_SELECT148RSVD51I2S_TXD67SDIO_D390GND91RSVD92GND78GND 77RSVD76GND93GND100GND79GND80GND83GND85GND86GND88GND89GND82GND84RSVD87ANT281ANT132GND31RSVD30GND44GND45RSVD 46GND145GND152GND43ETH _RX_CLK42ETH _RX_CTL39ETH _RXD137ETH _TXD036ETH _TXD134ETH _TXD333ETH _TX_CTL40ETH _RXD238ETH _RXD035ETH _TXD241ETH _RXD399GND98GND97GND96GND95GND94GND106GND105GND104GND103GND102GND101GND108GND107GND124GND123GND130GND129GND128GND127GND126GND125GND136GND135GND134GND133GND132GND131GND138GND137GND144GND143GND142GND141GND140GND139GND151GND150GND149GND148GND147GND146GND114GND113GND112GND111GND110GND109GND120GND119GND118GND117GND116GND115GND122GND121GNDTOBY-L4155RSVD153RSVD157RSVD156RSVD154RSVD158RSVD195CTS1193RTS1197RSVD196RSVD194RSVD198RSVD207I2S1_RXD206I2S1_TXD203SCL1201RSVD200RSVD217MMC_D2215MMC_CMD214MMC_D0212MMC_D1211MMC_RST_N209GND208I2S1_CLK222ETH _MDIO220ETH _INTR219GND204SDA1202RSVD199RSVD218MMC_CD_N216MMC_CLK213MMC_D3210V_MMC221V_ETH205I2S1_WA223ETH _MDC240ADC1241GND244RSVD246RSVD247GPIO8230MIC_GND232GND233MIC2_N235GND236MIC1_N238GND239ADC2225RSVD227SPK_P228SPK_N243RSVD245RSVD248GPIO7229GND231MIC_BIAS234MIC2_P237MIC1_P226GND242RSVD224RSVD162RXD2161TXD2160RXD1159TXD1168USB_ID163RSVD167RSVD166RSVD165RSVD164RSVD172VSIM1171USB_SSRX–170USB_SSRX+169SPI_MISO182SIM1_CLK181RSVD180RSVD179SPI_SCLK178SIM1_IO173SPI_CS177SIM1_RST176USB_SSTX–175USB_SSTX+174SPI_MOSI188RSVD183RSVD187RSVD186RSVD185RSVD184RSVD192RSVD191RSVD190RSVD189RSVDPin 93-152: GNDFigure 72: TOBY-L2 and TOBY-L4 series modules pad layout and pin assignmentTOBY modules are also form-factor compatible with the u-blox LISA, SARA and LARA cellular module families:although TOBY modules, LISA modules (33.2 x 22.4 mm, 76-pin LCC), SARA modules (26.0 x 16.0 mm, 96-pinLGA) and LARA modules (26.0 x 24.0 mm, 100-pin LGA) each have different form factors, the footprints for theTOBY, LISA, SARA and LARA modules have been developed to ensure layout compatibility.With the u-blox “nested design” solution, any TOBY, LISA, SARA or LARA module can be alternatively mountedon the same space of a single “nested” application board as described in the Nested Design Application Note[19].
