Board configuration and test points

The STEVAL-ISB68RX has several connectors and test points to ease access to key signals.
• P1 connector: micro-USB female receptacle for connection of the USB-to-I
• P2 connector/jumper: bridging point between the I
Jumpers placed as per
the connector turns into the I
• P3 & P4 connectors: grounding points for probing.
• P5 connector: auxiliary STWLC68JRH control signals access point. Programmable GPIOs, chip enable and
other STWLC68JRH pins are routed to this connector.
• J3 jumper (VBUS->VOUT): this jumper connects the 5 V supply rail of the USB to the output of
STWLC68JRH. It is used to communicate with STWLC68JRH when the receiver is not placed on a
transmitter (DC mode). Also used to supply the STWLC68JRH chip during OTP flashing. If closed, the
STEVAL-ISB68RX should not be put on transmitter.
• TP2: test-point connected to AC2 (rectifier input of STWLC68JRH).
• TP3: test-point connected to AC1 (rectifier input of STWLC68JRH).
• TP4: test-point connected to internal V1V8 LDO output (STWLC68JRH digital section supply rail).
• TP5: test-point connected to internal V5V0 LDO output (STWLC68JRH analog section supply rail).
• TP6: test-point connected to IEXT pin. Used to monitor the operation of the over-voltage protection (active
clamper).
• VRECT connector: rectifier output voltage (VRECT pins of STWLC68JRH)
• VOUT/GND connectors: main linear LDO regulator output voltage (VOUT pins of STWLC68JRH). Power
output rail of the wireless power receiver.
• COIL connector: terminals for the receiving coil.
