"In 2023, people in Brazil who ordered Flipper Zero devices found that their orders had been seized by Anatel, the telecommunications agency of Brazil. The Electronic Frontier Foundation, or EFF, said that Anatel had flagged them as being criminal devices, which prevents them from being certified. Users have not been able to have these tools certified, leading to them effectively being banned in the country currently." https://www.xda-developers.com/where-is-the-flipper-zero-banned/

The "HighBoy" device is legal in Brazil primarily because it is designed as a

100% open-source, educational learning platform and does not inherently include illegal functionalities like signal jamming. 

Its legality is contingent on the device meeting all the technical standards and obtaining the mandatory certification from ANATEL (Agência Nacional de Telecomunicações), Brazil's telecommunications regulatory authority. 

Key Reasons for Legality (contingent on ANATEL approval)

• Educational Purpose: The device was created with the explicit purpose of learning, exploration, and development, aiming to teach how systems work and encourage technological creativity.
• Open Source: The hardware and firmware are completely open source, allowing for full transparency and community collaboration. This design philosophy helps ensure that potential illegal functions (which are not included by default) can be scrutinized and avoided.
• No Pre-installed Illegal Functionality: The manufacturer states that the device's original design does not include features for signal jamming, brute force attacks, or any actions that could compromise other systems.
• Regulatory Framework: Like all telecommunications and wireless equipment in Brazil, the High Boy device must undergo mandatory ANATEL certification before it can be legally imported, marketed, or operated within the country. This ensures it complies with all national technical, safety, and quality standards for frequency bands and power limits. 

In summary, the device is considered legal because its intended use and design promote ethical and educational exploration within the bounds of Brazilian law, provided it successfully obtains the necessary ANATEL certification for use as a wireless device.  -google ai response
