ELECTRONICS
The TQ-Minimodule TQMLS1012AL with its LS1012A CPU is the central system component. It provides DDR3L SDRAM, eMMC,
NOR flash and EEPROM memory. All voltages required by the TQMLS1012AL are derived from the supply voltage of 3.3 V.
The available signals are routed to two connectors on the MBLS1012AL. More detailed information is to be taken from the
TQMLS1012AL User’s Manual. The boot behaviour of the TQMLS1012AL can be customised.
The required boot-mode configuration can be set with DIP switches, see section 4.4.

TQMLS1012AL
The TQ-Minimodule TQMLS1012AL with the LS1012A CPU is the central system component. It provides DDR3L SDRAM, NOR
flash and an EEPROM. All TQMLS1012AL internal voltages are derived from the 3.3 V supply voltage. Further information can be
found in the TQMLS1012AL User's Manual. The boot behaviour of the TQMLS1012AL can be modified. The configuration is
defined by DIP switches on the MBLS1012AL, see chapter 4.4. The available signals of the TQMLS1012AL are routed to the
MBLS1012AL. The signal assignment can be found in the TQMLS1012AL User's Manual.

Power supply
The MBLS1012AL has to be supplied with 16 V to 28 V at X21. The typical supply voltage is 24 V.
The MBLS1012AL has a maximum power consumption of approx. 51 W at the 24 V supply. This corresponds to a typical
maximum current consumption of 2.1 A. The power supply used must be dimensioned accordingly. In most applications,
however, the power consumption will be significantly lower. The largest part of the possible power consumption results from
the standard-compliant supply of the USB, PCIe and SATA (M.2) interfaces, as well as from the power available at the pin header.
3.3 V (1.5 A), 5 V (0.75 A) and 24 V (maximum current not defined) are available on pin header X22. The current drawn must be
added to the input current. It has to be ensured that the permissible limit values of the input circuit are not exceeded.
