Description
The Adafruit 4363 Airlift Bitsy ESP32 WiFi Co-Processor Breakout Board has an integrated TCP/IPTCP/IP is a suite of internet communication protocols. TCP (Transmission Control Protocol) is responsible for establishing reliable, ordered data delivery, and handling congestion control, while IP (Internet Protocol) focuses on routing packets of data to their destination. protocol stack that can give your ItsyBitsy or other microcontroller access to your WiFi network with the latest TLSTransport Layer Security/SSLSecure Sockets Layer encryption (it has root certificates pre-burned in). Having WiFi managed by a separate processor from your microcontroller means your code is simpler, you don't have to cache socket data, or compile in and debug an SSLSecure Sockets Layer library.
This breakout board has a u-blox NINA-W102 module (Datasheet) with an integrated ESP32-D0WDQ6-V3 SoCSystem On a Chip (32-Bit Dual-Core 240MHz CPU) and 2MB flash memory that provides 2.4GHz WiFi (802.11IEEE 802.11 is a set of protocol standards that define communication for a Wireless Local Area Network (WLAN). In order for WiFi to work between different devices, they all need to agree on how they are going to communicate. The current version of the standard is IEEE 802.11-2007, with many amendments such as 802.11a, 802.11b, 802.11g, and 802.11n.b/g/n) and Bluetooth (v4.2 BRBasic Rate/EDREnhanced Data Rate and BLEBluetooth Low Energy) with an SPISerial Peripheral Interface interface using a tri-state chip for MOSIMaster Out Slave In (MOSI) is the SPI data output line from the master device so you can share the SPISerial Peripheral Interface bus with other devices. The u-blox NINA-W102 is the same processor used on the Arduino Uno WiFi Rev2 and Arduino Nano 33 IoTInternet Of Things microcontroller boards. The Airlift board also has an RGBRed Green Blue LEDLight Emitting Diode that you can control with programming.
The ESP32 microcontroller in the Airlift can be programmed with Arduino code, MicroPython, or Adafruit's CircuitPython. It comes pre-programmed with firmware (GitHub) that is a slight variant of the Arduino WiFiNINA core, that you can use in CircuitPython to use this into a WiFi co-processsor over SPISerial Peripheral Interface with two control pins (an RST input Reset pin and BUSY output pin that lets your microcontroller know when its ready for more commands to be sent). Adafruit also has an Arduino library on GitHub.

| Security | CCMPCounter Mode Cipher Block Chaining Message Authentication Code Protocol (CCMP)/TKIPTemporal Key Integrity Protocol (TKIP) is a security protocol used in the IEEE 802.11 wireless networking standard. It was designed as an interim solution to replace WEP without requiring the replacement of legacy hardware. TKIP employs a per-packet key system that was more secure than the fixed key system used by WEP. However, TKIP itself is no longer considered secure and was deprecated in the 2012 revision of the 802.11 standard. It was superseded by Advanced Encryption Standard (AES)./WAPIWLAN Authentication and Privacy Infrastructure (WAPI) is a Chinese National Standard for Wireless LANs (GB 15629.11-2003)./WEPWired Equivalent Privacy (WEP) is an encryption security protocol for 802.11 wireless networks to protect the information you send and receive over a wireless network. WEP was ratified as a Wi-Fi security standard in September of 1999. |
| Encryption | AESAdvanced Encryption Standard (AES) is a specification for the encryption of electronic data established by the U.S. National Institute of Standards and Technology (NIST) in 2001.

Accessories
You can use the 3V 32u4, M0, or M4 ItsyBitsy microcontrollers in Arduino although the 32u4 will not be able to do very complex tasks or buffer a lot of data because they do not have a lot of RAM. Adafruit's ESP32SPI library requires a microcontroller with at least 128KB of RAMRandom Access Memory, so the 32u4 (2.5KB RAMRandom Access Memory) and SAMD21 (32KB RAMRandom Access Memory) will not work. If using CircuitPython which uses a lot of RAMRandom Access Memory, a SAMD51 M4 (128/192/256KB SRAMStatic Random Access Memory) minimum is required.
