Default State
Shorted Short this Jumper to supply 3.3V to the IO Domain (VDDIO) of the 0270x. Also use this jumper to
measure the current consumption of the IO Domain.
Shorted
Input of the internal 1.2V LDO, use this jumper to measure current consumption at the input of the
1.2V LDO
Shorted Input of the internal 2.5V LDO, use this jumper to measure current consumption at the input of the
2.5V LDO
Shorted
Output of the internal 1.2V LDO, use this jumper to measure current consumption at the output of
the 1.2V LDO
Shorted Supplies power to all the power rails in the 20706, use this jumper to measure current consumption
of the entire 20706 chip.
Shorted Connects CYW20706 BT_UART_RXD to FTDI TX
Shorted Connects CYW20706 BT_UART_TXD to FTDI RX
Shorted Connects CYW20706 BT_UART_CTS to FTDI RTS
Shorted Connects CYW20706 BT_UART_RTS to FTDI CTS
