Power Arrangement
The TPP2 can be powered directly through two terminal blocks located next to the
RJ45 jack. The board expects reg5V power. We recommend the power
supply with at least 1-1.5A output current capability. 300mA of this power budget
will be used for the TPP2 alone. The
Wi-Fi add-on, if present, will consume
an additional 300mA of current. Installed
will also add to the overall power
consumption.
Alternatively, the TPP2 can be powered using power supply Tibbits (such as
,
, etc.), in which case there will be no need to c5V power to the
board.
Some Tibbits (such as
or
) require addi15V and -15V power to
function. These voltages are not generated by the TPP2 and can't be applied
externally. The only way to produce them is to install a special power Tibbit
The

Ethernet Port
The Ethernet port of the TPP2 is of 10/100BaseT type.
The connector is of RJ45 type, pin assignment is as follows:

MD and RST Buttons
The function of the MD button is described in
Pressing the reset button causes a hardware reset.
Both buttons face
right
on Tibbo Project PCBs. For assembly inside a Tibbo Project
Box (TPB), a TPP must be outfitted with a so-called MD/RST button PCB. This is a
small PCB with two buttons facing upward. When plugged into the TPP board, these
buttons work in parallel with the buttons of the TPP board.
The MD/RTS PCB is necessary only when you assemble the TPP board into the Tibbo
Project Box. Hence, the MD/RST PCB is supplied as a part of the TPB kit, not the
Tibbo Project PCB.
