WROOM, SOLO, WROVER, and PICO Modules
|
||
=====================================
|
||
|
||
This is a family of ESP32-based modules with some integrated key components, including a crystal oscillator and an antenna matching circuit. The modules constitute ready-made solutions for integration into final products. If combined with a few extra components, such as a programming interface, bootstrapping resistors, and pin headers, these modules can also be used for evaluation of ESP32's functionality.
|
||
|
||
The key characteristics of these modules are summarized in the table below. Some additional details are covered in the following sections.

Development Boards
|
||
==================
|
||
|
||
Depending on the intended functionality, different development boards feature:
|
||
|
||
- Access to different ESP32 GPIO pins.
|
||
- Different interfaces: USB, JTAG.
|
||
- Different peripherals: touchpads, LCD screens, SD card slots, female headers for camera modules, etc.

ESP32-PICO-KIT V4.1
|
||
-------------------
|
||
|
||
This is the smallest available ESP32-based development board. It features all the components for direct connection to a computer's USB port as well as pin headers for plugging into a mini breadboard.
|
||
|
||
The board is equipped with the `ESP32-PICO-D4`_ module. With such a module, the creation of a fully functional development board required only a few external components that fit on a PCB as small as 20 x 52 mm. The external components include antenna, LDO, USB-UART bridge, and two buttons for reset and activation of Firmware Download mode.

|
||
|
||
Power can be supplied either via USB or via a standard 5 mm power supply jack. A power source can be selected with a jumper and can be turned on/off with a separate switch.
|
||
|
||
This version of the ESP-WROVER-KIT board integrates the ESP-WROVER-B module that has 8 MB PSRAM for flexible extended storage and data processing capabilities. The board can accommodate other versions of ESP modules described in :ref:`esp-wroom-solo-wrover-modules`.
|
||
|
||
Comparing to :ref:`esp-modules-and-boards-esp-wrover-kit-v3`, this board has the following design changes:
|
||
|
||
- JP8, JP11, and JP13 have been combined into a single JP2.
|
||
- USB connector has been changed to DIP type and moved to the lower right corner of the board.
|
||
- R61 has been changed to a Zero-ohm resistor.
|
||
- Some components have been replaced with functional equivalents based on test results and sourcing options, e.g., the EN and Boot buttons.
