TinyCAD
TinyCAD is a an open source program for drawing circuit diagrams which runs under Windows. Do not pay for TinyCAD, it is free and always will be. There are no licensed sellers of TinyCAD. Creating libraries of circuit symbols in TinyCAD is easy, but time-consuming. If you have some symbols you feel might benefit other TinyCAD users, then why not upload the symbols to this site to allow other users to download them? The TinyCAD manual is included in the installer but can also be read on-line as part of the TinyCAD wiki. If you feel this manual could be updated in any way, then please go-ahead and edit the Wiki for the benefit of others. There are tutorials on the Github site on how to edit Wikis.

RIOT
RIOT powers the Internet of Things like Linux powers the Internet. RIOT is a free, open source operating system developed by a grassroots community gathering companies, academia, and hobbyists, distributed all around the world. RIOT supports most low-power IoT devices, microcontroller architectures (32-bit, 16-bit, 8-bit), and external devices. RIOT aims to implement all relevant open standards supporting an Internet of Things that is connected, secure, durable & privacy-friendly. RIOT supports DTLS transport layer security, IEEE 802.15.4 encryption, Secure Firmware Updates (SUIT), multiple cryptographic packages, and crypto secure elements. RIOT is modular to adapt to application needs. We aim to support all common network technologies and Internet standards. RIOT is open to new developments and often an early adaptor in networking.
