CapibaraZero open-source firmware aims to offer a low-cost alternative to Flipper Zero for ESP32-S3-based hardware platforms and soon other gizmos with ESP32 wireless microcontrollers, notably the LilyGO T-Embed CC1101, similar to the original T-Embed with ESP32-S3 WiSoC, but also featuring a Texas Instruments CC1101 Sub-GHz microcontroller and an NXP PN532 NFC/RFID module. The Flipper Zero is a popular portable multi-tool for pentesters and hardware hackers based on STMicro STM32WB55 Bluetooth 5 LE & 802.15.4 wireless microcontroller and a TI CC1101 Sub-Ghz MCU that got involved in controversies such as a ban proposal in Canada last year due to its (dubious) potential use for car theft. Since then we’ve seen several alternatives such as Monstatek M1 (that’s yet to be delivered to backers…) and HackBat open-source hardware with Raspberry Pi RP2040,  ESP8266 WiFi module, and the CC1101 RF transceiver. The CapibaraZero firmware offers another way to create your own cheap Flipper [...]

LILYGO launched the T-Embed CC1101, built around the ESP32-S3 Dual-core LX7. It supports Wi-Fi, BLE 5, and Sub-GHz wireless communication, targeting remote and low-power IoT projects. The ESP32-S3 microcontroller is paired with 16MB of Flash memory and 8MB of PSRAM. The CC1101 chip operates across frequency bands of 300-348 MHz, 387-464 MHz, and 779-928 MHz, […]
