Hologram on Thursday launched Nova, the first open source modem for cellular connectivity. Nova is a USB cellular modem purpose-built for Internet of Things development. Its Hologram software tools are compatible with most single board computers, such as Raspberry Pi. The Nova modem is open source and unlocked, so its use is not limited to Hologram's SIMs. Though it targets the developer community, it has potential uses for everyone from makers to system architects. It sells for $49. Nova comes with the Hologram Python SDK.
