The Jornada was a line of personal digital assistants or PDAs manufactured by Hewlett-Packard.

All Jornada models ran Microsoft Operating Systems that were based on Windows CE.

Introduced in 1998, the Jornada 820 ran on the Windows CE 2.11 operating system, Handheld PC Professional Edition 3.0, had a small trackpad with two buttons and a built-in miniature keyboard.

The HP HVGA screen operated at 256 colours with a driver update providing 64K color support.

It also ran on HPC2000, however the package differed from the higher end 720 and 728, making the 710 a lower cost alternative.

It runs on the Windows CE 3.0 based Handheld PC 2000 and contains a slightly higher OS revision than the 710 or 720, providing the user with native PPTP VPN functionality.

The Jornada 728 contained a slightly higher spec battery package, giving it a 14 hour runtime, and was also cosmetically different from the previous 700 series releases by using light purple and grey tones instead of the monochromatic blue chassis of its predecessors.

It featured 16 MB of RAM, a Type I CompactFlash slot,[6] a 256 color screen, and a 133 MHz SH3 processor.

The 520 allowed for an optional flip cover like the 540 models, but was only capable of supporting a serial cable for synchronization.

It debuted in October 2001, and featured a reflective LCD screen with an ambient light sensor, and had a completely redone form factor.

The phone was a European GSM Dual band device capable of accessing GPRS.

HP Labs in Bristol, United Kingdom, used the GPRS Jornada devices initially with the 568 and later the 928 to create some of the first connected solutions and wearable computing in Bristol ranging from interactive tours of the city[7] to instant language translation [8] trials were also conducted by HP senior executives with major clients such as Disney to explore the use of the technologies in business applications.

Hewlett-Packard's Appliances and Calculators Organization (ACO) in Melbourne, Australia, also worked on the HP Jornada X25 (F1904A) aka "Calypso", a PDA based on a customized Linux version provided by Lineo Australia and Taiwan.
