Ọrụ ZSWatch na-emepe smartwatch mepere emepe dabere na mgbawa Nordic Semiconductor nRF52833, nke ejiri microprocessor ARM Cortex-M4 na-akwado Bluetooth 5.1. Atụmatụ na nhazi nke bọọdụ sekit a na-ebipụta (na usoro kicad), yana ihe nlereanya maka ibipụta ụlọ na ọdụ ụgbọ mmiri na ngwa nbipute 3D dị maka nbudata. Akụrụngwa dabere na RTOS Zephyr mepere emepe. A na-akwado ijikọ smartwatches na smartphones dabere na ikpo okwu gam akporo. A na-ekesa mmepe nke ọrụ a n'okpuru ikikere MIT.
A na-emepụta sọftụwia na ngwaike akọwapụtara nke ọma maka ọrụ a. Na mgbakwunye na mgbawa nRF52833 BLE, ngwaọrụ ahụ gụnyere ihuenyo 1.28-inch (IPS TFT 240 × 240), ngwa ngwa nwere ọrụ pedometer, ihe mmetụta pulse, moto vibration, 8 MB Flash, na batrị Li-Po 220 mAh . Enwere bọtịnụ atọ maka njikwa, a na-ejikwa iko sapphire chebe ihuenyo ahụ. Nlereanya nke abụọ emelitere nke abụọ dịkwa na mmepe, nke a na-amata site na iji mgbawa nRF5340 na-arụ ọrụ karịa nke dabere na ARM Cortex-M33 processor na ọnụnọ ihuenyo mmetụ.
Edere sọftụwia ahụ na C ma na-arụ ọrụ n'okpuru sistemụ arụmọrụ Zephyr ozugbo (RTOS), nke emepụtara maka ngwaọrụ ịntanetị nke ihe n'okpuru nkwado nke Linux Foundation na ntinye aka nke Intel, Linaro, NXP Semiconductors/Freescale, Synopsys na Nordic Semiconductor. . Emebere Zephyr isi ka ọ rie obere akụrụngwa (site na 8 ruo 512 KB nke RAM). A na-enye usoro niile naanị otu oghere adreesị mebere zuru ụwa ọnụ (SASOS, Sistemụ Ọrụ Oghere Otu Address). A na-ejikọta koodu akọwapụtara ngwa na kernel maka ngwa ka ọ mepụta monolithic executable nke enwere ike ibu ma rụọ ya na ngwaike akọwapụtara. A na-ekpebi akụrụngwa sistemụ niile n'oge a na-achịkọta, yana naanị ikike kernel ndị achọrọ iji mee ngwa a gụnyere na onyonyo sistemụ.
