ESP32-S2 Kaluga Dev Kit (v1.3) featuring WROVER
The ESP32-S2-Kaluga-1 version 1.3 kit is a full featured development kit by Espressif for the ESP32-S2 that comes with everything but the kitchen sink! From TFTs to touch panels, this dev board has it all. Espressif designed this kit to demonstrate the ESP32-S2’s human-computer interaction functionalities and provide the users with the tools for development of human-computer interaction applications based on their new WiFi modules with the ESP32-S2 chip
Version 1.3 was released starting in Summer 2020. The original version, 1.2, also has a CircuitPython port. The pinouts are slightly different between the two versions. You can tell which version you have by the silkscreen on the bottom of the main board.
The Kaluga comes with a WROVER module, which has 2 MB (16 Mbit) PSRAM mounted for a roomy development environment!
The micro USB connector on the Kaluga is wired through a CP210x USB to serial converter chip for debugging and programming. The native USB is not available on a USB connector - instead you’ll want to pick up a Micro B USB connector breakout, Type C USB connector breakout or USB data cable and hand-wire D19/D20 to D- and D+ pads.
There are many ways of how the ESP32-S2’s abundant functionalities can be used. For starters, the possible use cases may include:
- Smart home: From simplest smart lighting, smart door locks, smart sockets, to video streaming devices, security cameras, OTT devices, and home appliances
- Battery-powered equipment: Wi-Fi mesh sensor networks, Wi-Fi-networked toys, wearable devices, health management equipment
- Industrial automation equipment: Wireless control and robot technology, intelligent lighting, HVAC control equipment, etc.
- Retail and catering industry: POS machines and service robots
Each order comes with a nice boxed kit containing:
- Main board: ESP32-S2-Kaluga-1
- ESP-LyraT-8311A audio player extension board
- ESP-LyraP-TouchA touch panel extension board
- ESP-LyraP-LCD32 3.2” LCD screen extension board
- ESP-LyraP-CAM camera board extension board

This is the latest unstable release of CircuitPython that will work with the ESP32-S2 Kaluga Dev Kit (v1.3) featuring WROVER.
Unstable builds have the latest features but are more likely to have critical bugs.
Built-in modules available: _bleio, adafruit_bus_device, adafruit_pixelbuf, aesio, alarm, analogio, atexit, audiobusio, audiocore, audiomixer, binascii, bitbangio, bitmaptools, board, busio, canio, countio, digitalio, displayio, dualbank, errno, fontio, framebufferio, frequencyio, getpass, imagecapture, ipaddress, json, keypad, math, microcontroller, msgpack, neopixel_write, nvm, onewireio, os, paralleldisplay, ps2io, pulseio, pwmio, qrio, rainbowio, random, re, rgbmatrix, rotaryio, rtc, sdcardio, sharpdisplay, socketpool, ssl, storage, struct, supervisor, synthio, terminalio, time, touchio, traceback, ulab, usb_cdc, usb_hid, usb_midi, vectorio, watchdog, wifi
Every time we commit new code to CircuitPython we automatically build binaries for each board and language. The binaries are stored on Amazon S3, organized by board, and then by language. Try them if you want the absolute latest and are feeling daring or want to see if a problem has been fixed.
All previous releases are listed on GitHub, with release notes, and are available for download from Amazon S3. They are handy for testing, but otherwise we recommend using the latest stable release. Some older GitHub release pages include the same binaries for downloading. But we have discontinued including binaries as assets on newer release pages because of the large number of files for each release.
