SQLite is a software library that implements a self-contained, serverless, zero-configuration, transactional SQL database engine. SQLite is the most widely deployed SQL database engine in the world. It is faster than popular client/server database engines. 
 
SQLite is popular choice for the database engine in cellphones, PDAs, MP3 players, set-top boxes, and other electronic gadgets. SQLite has a small code footprint, makes efficient use of memory, disk space, and disk bandwidth, is highly reliable, and requires no maintenance from a Database Administrator.

The wolfSSL embedded SSL library (formerly CyaSSL) is a lightweight SSL/TLS library written in ANSI C and targeted for embedded, RTOS, and resource-constrained environments - primarily because of its small size, speed, and feature set. It is commonly used in standard operating environments as well because of its royalty-free pricing and excellent cross platform support. 
 
wolfSSL supports industry standards up to the current TLS 1.3 and DTLS 1.2 levels, is up to 20 times smaller than OpenSSL, and offers progressive ciphers such as ChaCha20, Curve25519, NTRU, and Blake2b. User benchmarking and feedback reports dramatically better performance when using wolfSSL over OpenSSL.

The original uClinux (you-see-linux) was a derivative of Linux 2.0 kernel intended for microcontrollers without Memory Management Units (MMUs). However, the Linux/Microcontroller Project has grown both in brand recognition and coverage of processor architectures. Today's uClinux as an operating system includes Linux kernel releases for 2.0 2.4 and 2.6 as well as a collection of user applications, libraries and tool chains. uClinux is mostly used in Embedded and Gaming device. uClinux is ported to Cisco routers, Motorola, Intel and many other devices and microcontrollers.

Dqlite is a fast, embedded, persistent SQL database with Raft consensus that is perfect for fault-tolerant IoT and Edge devices. Dqlite (“distributed SQLite”) extends SQLite across a cluster of machines, with automatic failover and high-availability to keep your application running. It uses C-Raft, an optimised Raft implementation in C, to gain high-performance transactional consensus and fault tolerance while preserving SQlite’s outstanding efficiency and tiny footprint.

EJDB is an embedded JSON database engine. It aims to be a fast MongoDB-like library which can be embedded into C/C++ applications. It features collection-level write locking, collection level transactions, string token matching queries, and a Node.js binding. It is the C library based on modified version of Tokyo Cabinet. JSON representation of queries and data implemented with API based on C BSON

Pycopy aims to develop and maintain a minimalist, lightweight, and extensible implementation of Python(-compatible) language. Pycopy to CPython is a similar thing as Scheme to Common Lisp. Pycopy works similarly well in the cloud, on desktop systems, on small embedded systems, and scales all the way down to microcontrollers.  It is originally based on MicroPython.
