Target Board for RX23W module
5.8
External Power-Supply Header
When more current is required than the USB is capable of supplying, use the external power-supply header
(J1) to supply power. The usable voltage is 3.3 V. When this header is to be used, remove the pattern for
cutting (SS19) on the soldered side, electrically separating the emulator from the target. Figure 5-4 shows the
position of the pattern for cutting. Figure 5-5 shows the position of the external power-supply header (the
actual header component is not mounted on the board as shipped).
