.. _esp-modules-and-boards-esp-wrover-kit-v3:
|
||||
|

This revision of ESP32 WROVER KIT introduced several changes to conditioning and interlocking of signals to the bootstrapping pins. A zero Ohm resistor (R166) has been addedd between WROVER/WROOM module and VDD33 net, which can be desoldered or replaced with a shunt resistor for current measurement. This should facilitate power consumption analysis in varius operation modes of ESP32. Refer to schematic - the changes are enclosed in green border.

The first release of ESP-WROVER-KIT shipped with ESP32-WROVER module installed by default. This release also introduced several design changes to conditioning and interlocking of signals to the bootstrapping pins. Also, a zero Ohm resistor (R166) has been added between WROVER/WROOM module and VDD33 net, which can be desoldered, or replaced with a shunt resistor, for current measurement. This is intended to facilitate power consumption analysis in various operation modes of ESP32. Refer to schematic - the changes are enclosed in green border.
