Getting Started Manual 13
2.3.3 Connect Power
When all other connections have been made, you can connect power to the BL1810.
Hook up the connector from the wall transformer to header J1 on the BL1810 as shown in
Figure 3. The orientation of this connector is not important since the VIN (positive) volt-
age is the middle pin, and GND is available on both ends of the three-pin header J1.
Plug in the wall transformer. The BL1810 and the Prototyping Board are ready to be used.
NOTE: A RESET button is provided on the Prototyping Board (see Figure 3) to allow
hardware reset without disconnecting power.
To power down the BL1810, unplug the power connector from J1. You should disconnect
power before making any circuit adjustments in the prototyping area, changing any con-
nections to the board, or removing the BL1810 from the Prototyping Board.
2.3.3.1 Overseas Development Kits
Development kits sold outside North America include a header connector that may be
connected to 3-pin header J1 on the BL1810. The connector may be attached either way as
long as it is not offset to one side. The red and black wires from the connector can then be
connected to the positive and negative connections on your power supply. The power sup-
ply should deliver 7.5 V–25 V DC at 5 W.
