TS-4900 TS-Socket
From embeddedTS Manuals
- ↑ EXT_RESET# is an open-drain input used to reboot the CPU.
- ↑ This is an output which can be manipulated in the #Syscon. This pin can optionally be connected to control a FET to a separate 5V rail for USB to allow software to reset USB devices.
- ↑ 3.0 3.1 3.2 3.3 3.4 3.5 This SD interface is the same one used by the MicroSD on the TS-4900. Only one can be used at a time.
- ↑ OFF_BD_RESET# is an output from the System-on-Module (SoM) that automatically sends a reset signal when the unit powers up or reboots. It can be connected to any IC on the base board that requires a reset.
- ↑ 5.0 5.1 5.2 5.3 The 5V power pins should each be connected to a 5V source.
- ↑ This is used during production to boot to an offboard SPI flash. This pin should typically be left unconnected.
- ↑ 7.0 7.1 The TS-4900 regulates a 3.3V rail which can source up to 700mA. Designs should target a 300mA max if they intend to use other SoMs.
- ↑ This pin is used as a test point to verify the RAM has a correct voltage for debugging
