  • Page 13 PB1 is connected only to PL606-1 to be externally wired to any desired GPIO pin on any other connector’s header. PB2 is connected to PL606-2 and goes directly to the WL865E4-P RESET#, an active low HW Reset pin, press and release it to unconditionally reset the module.
  • Page 14 VDD_IO, no matter its value. 3V3 is to be considered the default. The WL865E4-P can have different VIO voltage value with respect to core. This is selected on Jumper headers PL302 and PL301. If no jumpers are plugged into these headers the only ON position of the switch is not enough to correctly powering the module.
  • Page 15 The PL301 can be used also as an insertion point to measure current consumption of the module or for external power supply use. The WL865E4-P EVB has three different LED’s on the left part shown in Figure 3-11, each LED indicates a specific status: LED Red ON–...
