ESP32 Marauder Kit

ESP32 Marauder Kit

The ESP32 Marauder Kit is a bundle of hardware components that allow a user to assemble a fully functional ESP32 Marauder. All that is required from the user is that they must provide their own Adafruit Huzzah32 flashed with the ESP32 Marauder firmware, and a 3.7V LiPo battery compatible with the Huzzah32.

Firmware Install Options (Pick One)

You have two options for installing firmware. If you want to hit the ground running as fast as possible with minimal effort, I recommend Option 1. If you want to get to know the source code and the build process, try Option 2. If Option 2 fails, try Option 1.

Installing Firmware Over The Air (OTA) (Option 1)(easy)

1. Follow the instructions under Arduino IDE Setup
2. Open the Arduino IDE
3. Plug your ESP32 Marauder Kit into a USB port using a micro USB data cable and select the COM port under Tools>Port
4. Select the appropriate ESP32 module under Tools>Boards
   • If you are using the ESP32 Marauder Kit: Adafruit ESP32 Feather
5. For partition scheme, select Minimal SPIFFS (Large APPS with OTA)
6. Copy the ESP32 Marauder OTA Upload firmware source from here into your Arduino IDE window
7. Click the Upload button in the top left corner of the Arduino IDE and let the code compile and upload to the ESP32 Marauder
8. Download the latest release of the ESP32 Marauder firmware
   • The file you want will have _kit at the end of its name
9. Connect to the ESP32 Marauder OTA WiFi network
   • Network ESSID: MarauderOTA
   • Network Password: justcallmekoko
10. Open your web browser application
11. Navigate to http://192.168.4.1
12. Login using the provided credentials
    • Username: admin
    • Password: admin
13. Once you are logged in, refresh the web page
14. Browse for the firmware file you downloaded
15. Click the Update button
    • The ESP32 Marauder will automatically reboot once the update process is complete

Building and Installing Firmware from source (Option 2)(not easy)

To build the ESP32 Marauder firmware from source and install it on the Adafruit Huzzah32, follow the instructions under Installing Firmware.

Assembling Hardware

1. Solder the male header pins included with your Adafruit Huzzah32 to the Huzzah32 board

3. Connect your 3.7V LiPo battery to the JST connector of the Huzzah32
   • Note: Ensure the power switch of the ESP32 Marauder Kit PCB is in the off position
4. Using some sort of adhesive such as double sided tape or glue, fix the 3.7V LiPo battery to the inside of the Marauder enclosure

5. Using the 4 included M2.5 x 5mm screws, screw the ESP32 Marauder PCB to the enclosure so that the TFT Touch screen faces outward

Using Your ESP32 Marauder Kit

Now that you have assembled and programmed your Adafruit Huzzah32, you should have a fully functional ESP32 Marauder. To start getting familiar with its capabilities, read through the Applications.
