The Teya Go runs on PAX A77 hardware (Android 14, PCI PTS 7, no printer). The Teya Pro runs on Sunmi P2 Pro hardware (Android 7.1, PCI PTS 5.0, built-in Seiko printer). Both are Teya terminals. Here is the full comparison.
Both Teya terminals are Android smart devices made by different manufacturers. The Teya Go uses PAX A77 hardware (made by PAX Technology); the Teya Pro uses Sunmi P2 Pro hardware (made by Sunmi Technology). Teya white-labels both and sells them under its own commercial names. Here is a full comparison of the underlying hardware.
Teya Go = PAX A77. Teya's commercial name for the PAX A77 terminal is the "Teya Go." The PAX A77 is manufactured by PAX Technology. Teya ships it pre-configured with the Teya payment platform firmware at £69 outright.
Teya Pro = Sunmi P2 Pro. Teya's commercial name for the Sunmi P2 Pro terminal is the "Teya Pro." The Sunmi P2 Pro is manufactured by Sunmi Technology. Teya ships it pre-configured at £139 outright or £14.99/month.
Both are PAX or Sunmi hardware running Teya's payment software on top. The hardware platform matters when comparing certifications, OS versions, and physical features.

The most practical difference for most businesses: the Sunmi P2 Pro (Teya Pro) has a built-in Seiko thermal printer. The PAX A77 (Teya Go) does not. If you need to print paper receipts at the point of sale, the Teya Pro handles this without a separate printer. With the Teya Go, you would rely on digital receipts (SMS or email) or a separate receipt printer.
The PAX A77 (Teya Go) runs Android 14. The Sunmi P2 Pro (Teya Pro) runs Android 7.1. A newer Android version means more up-to-date OS-level security patches and broader app compatibility at the OS level. Payment terminals run heavily customised firmware on top of Android, so the underlying version matters less than it would on a consumer device, but the newer Android on the Teya Go is a noteworthy difference.
PCI PTS (PIN Transaction Security) is the payment terminal security standard. A higher version indicates a newer and more stringent certification.
Both are currently accepted by payment networks. Older PCI PTS certifications are phased out over time, so the Teya Go's PTS 7 certification has a longer useful compliance lifecycle ahead of it.
The Teya Go (PAX A77) has 4G, WiFi 5GHz, and Bluetooth 5.0, plus built-in GPS (GPS, GLONASS, and BEIDOU). It works on mobile data without a Wi-Fi network, making it fully field-ready. The Teya Pro (Sunmi P2 Pro) uses Wi-Fi as its primary connection with 4G as a backup, but has no GPS. For fixed till setups this makes no practical difference. For mobile businesses (market stalls, tradespeople, deliveries, or any workflow needing location awareness or barcode scanning) the Teya Go's hardware capability is a clear advantage.
The Sunmi P2 Pro has a marginally larger screen (5.99 inch vs 5.5 inch). Both are full-size Android touchscreens suitable for ePOS-integrated workflows.

PAX Technology makes many different terminal models. The PAX A920Pro, for example, is a different device to the PAX A77 and is used by other payment providers in the UK. The PAX A77 is specifically the hardware platform behind the Teya Go. If you encounter references to other PAX devices, they are separate products and not related to the Teya Go.
