Page 6: Power Supply
3.1 Power Supply It is intended that the TWR-SER2 be powered from a source in an assembled Tower System via the 5.0V and 3.3V supplies on the TWR-ELEV. This includes the functional Tower Elevator USB power connector, a capable MCU/MPU controller module, or other Tower System module capable of providing power to the entire Tower System. -

Remove to Isolate CAN_RX 3.7 Elevator Connections The TWR-SER2 features two expansion card-edge connectors that interface to Elevator boards in a Tower System: the Primary and Secondary Elevator connectors. Table 2 provides the pinout for the Primary and Secondary Elevator Connector. An “X” in the “Used” column indicated that there is a connection from the TWR-MEM to that pin on the Elevator connector. - Page 11 TWR-SER2 Primary Connector Name Usage Used Jmp Name Usage Used I2S0_DOUT_SCK GPIO2 / SDHC_D1 I2S0_DOUT_WS GPIO3 I2S0_DIN0 CLKIN0 RMII_REF_CLK I2S0_DOUT0 CLKOUT1 Ground Ground Ground Ground DAC1 DAC0 TMR3 TMR1 TMR2 TMR0 GPIO4 USB_VBUS_EN GPIO6 USB_VBUS_OC 3.3V 3.3V Power 3.3V 3.3V Power...
