(2.54mm) pin headers to allow current measurement device connections (ampere meter, scope probe). ? when an external voltage source (no on-board battery) is used on j3, change the jumper position on j1 to pin 1 and pin 2 (vext). ? when the on-board aa battery is used, change the jumper position on j1 to pin 2 and pin 3 (vbat). ? to set the r-78s into sleep mode, apply the provided jumper on both pins of j6 (ctrl to gnd). j3 j1 vext vext vbat off on i_in i_out vbat gnd gnd ctrl vout gnd d- d+ gnd j4 j6 j7 j5 j8 con1 for evaluation only r-78sxx-0.1-evm-1 s1 u1 j2 bat1 evaluation module specifcations (measured @ ta= 25c, 1.5vin, full load after warm up unless otherwise stated) r-78s3.3-0.1-evm-1
