CapibaraZero Firmware With ESP32-S3 Hardware Enables Low Cost Flipper Zero alternative

The open-source tech landscape continues to innovate, and the release of the CapibaraZero firmware marks another breakthrough.

Designed for ESP32-S3-based hardware platforms, CapibaraZero provides a low-cost alternative to the highly popular—but expensive—Flipper Zero, a multifunctional tool for penetration testers, ethical hackers, and tech enthusiasts.

With its affordable hardware requirements and flexible firmware, CapibaraZero opens up more avenues for experimentation and learning without breaking the bank.

What is CapibaraZero?

CapibaraZero is an open-source firmware that brings Flipper Zero-like functionalities to devices based on the ESP32-S3 microcontroller.

While Flipper Zero, powered by the STM32WB55 Bluetooth and CC1101 Sub-GHz chips, has seen widespread adoption, its price point and controversies, such as proposed bans in Canada for its alleged misuse, have made alternatives appealing.

The CapibaraZero firmware targets cost-effective hardware such as the LilyGO T-Embed CC1101, a compact ESP32-S3 device packed with impressive features.

LilyGO T-Embed CC1101

The LilyGO T-Embed CC1101 platform integrates the essential components of CapibaraZero, making it one of the easiest and most accessible options for enthusiasts and developers. Here’s what it offers:

  • Processor & Memory: Powered by ESP32-S3-WROOM-1U with a dual-core Xtensa LX7 processor, 8MB PSRAM, and 16MB flash.
  • Connectivity: Wi-Fi 4, Bluetooth 5.0, Texas Instruments CC1101 for Sub-GHz communication, and an NXP PN532 NFC/RFID transceiver.
  • Display: A vibrant 1.9-inch IPS TFT LCD with 320 x 170 resolution.
  • Additional Features: Infrared receiver/transmitter, rotary encoder, built-in microphone, RGB LEDs, and a 1300mAh LiPo battery.

The device provides a wide range of functionality similar to the Flipper Zero for a fraction of the price, with units available on platforms like Amazon for $60 or AliExpress for $67.

CapibaraZero Firmware Features

Although still in Beta, CapibaraZero has already implemented key functionalities, including:

  • Wireless Capabilities: Wi-Fi, Bluetooth Low Energy (BLE), and Sub-GHz transceiver support.
  • NFC/RFID: Supported via the PN532 module.
  • Infrared Communication: IR receiver and transmitter for remote control emulation.
  • BadUSB & Network Attacks: Limited pentesting tools for testing vulnerabilities.

According to the CNX report, CapibaraZero firmware supports other ESP32-S3 boards such as the Arduino Nano ESP32 and ESP32-S3-DevKitC-1.

However, external modules are needed to fully replicate the Flipper Zero’s feature set, such as adding displays, NFC, or Sub-GHz radios.

Priced significantly lower than the $169 Flipper Zero, the LilyGO T-Embed CC1101 running CapibaraZero firmware offers a budget-friendly but powerful alternative.

While it may not boast the same level of community support or polished user experience, its open-source philosophy and flexibility make it a compelling choice for developers and hackers seeking both affordability and functionality.

With CapibaraZero’s ongoing development, tech enthusiasts now have a promising way to explore hardware hacking and pen-testing without the high cost of entry.
