The SSI-19 payload was, as needed, a very barebones set of electronics. It included an APRS BigRedBee transmitter using the callsign of balloons team member Iskender Kushan (KK6MIR), a GPS for position reporting, a sizable lithium-ion battery, and a heater made of nickel-chromium (nichrome) wire. In total, the payload had a mass of about 365g. It was the first balloon to be launched during the launch of SSI-19, SSI-20, and SSI-21. CNSP graciously brought their mass-flow meter to fill the SSI-19 latex balloon to a precise lift capacity (a mission-critical aspect of this launch).
