To help developers get started, Moddable Zero provides reference hardware with a small touchscreen for $20 plus shipping and tax, aiming to keep the hardware affordable:
All the components in Moddable Zero have been selected to keep the cost low. The two main components are the NodeMCU board and the touch screen. The NodeMCU module carries the ESP8266, Wi-Fi antenna, Flash ROM, FTDI chip, and USB connector. The touch screen is an unbranded QVGA (240 x 320) display with 16-bit pixels driven by an ILI9341 display controller and an XPT2046 resistive touch controller. We’d like to use a capacitive touch display, but the prices are still considerably higher. That said, our touch driver delivers reliable touch input with the XPT2046.

Moddable has ES6 without eval, without the parser, running in 48K of ROM and 48K of RAM. That's pretty impressive. They're using some of the object.freeze affordances in ES6 to put things in ROM. It's amazing.
