WF111 development kit design information

The WF111 is a fully integrated single 2.4 GHz band 802.11 b/g/n module designed for portable and battery-powered applications requiring Wi-Fi connectivity. The WF111 integrates an IEEE 802.11 b/g/n radio, antenna or U.FL antenna connector, and SDIO host interface. It provides a low-cost and simple Wi-Fi solution for devices running an operating system and an onboard TCP/IP stack, but still offers the advantages of modules - small size, certification and ease of integration. Silicon Labs also provides WF111 drivers for Linux and Android operating systems. WF111 has hardware support for Wi-Fi encryption protocols.

Bluetooth BT121 Development Kit Design Document

BT121 is a Bluetooth dual-mode module suitable for applications requiring Bluetooth LE and BR/EDR connections. It can connect to older devices that only support Bluetooth SPP or Apple® iAP2 profiles as well as devices that support Bluetooth LE. The BT121 integrates a high-performance Bluetooth radio, a low-power ARM Cortex microcontroller and Bluegiga Bluetooth dual-mode stack software, requiring no RF or Bluetooth software development, making it very easy to use. The BT121 can be used as a modem with a separate host MCU, but applications can also be embedded into the built-in ARM® Cortex® MCU with the Bluegiga BGScriptTM scripting language.

The Skull CTF: Guessing Skull Game Tool

The Skull is a Capture the Flag (CTF) puzzle that invites you to explore the innards of the AVR architecture. It has multiple stages that may keep you busy for days or even weeks as you flex your brain muscles and apply them to her riddles. Unless, of course, your mind loses its grip on reality and you fall into a swirling void of madness with no anchor. In this case, it may take you longer. To keep your head above water, you need three things: the ability to read and understand Arduino code, a willingness to spend some time reading the ATtiny45 datasheet, and basic programming skills.
