Table 1.2 Power supply, Dimensions and Environmental Specifications of Solution Engine2
Table 1.3 Permissible Current Supply to the Outside by Solution Engine2 Supply Voltages
Supply voltage
5V
3.3V
[Notes]
(1) Table 1.2 shows the maximum dissipation current of T-Engine (comprising the CPU board, LCD board, debug
board and I/O board) without external devices.
(2) Table 1.3 shows the sum of permissible current in all the powered devices on Solution Engine2.
when a current of 100mA is used for the PCMCIA card supply voltage (5V), the currents of the USB bus power or
extension slot is 150mA (250mA to 100mA). This is true for the supply voltage 3.3V.
(3) When the PCMCIS card, etc. is powered from the internal power supply of Solution Engine2, the current must not
exceed the permissible current of each power supply shown in Table 1.3. Otherwise, there is a risk of electric
shock, heat, or fire.
