LILYGO's $150 T-Display K230 Runs Linux on RISC-V With LoRa Built In, and Its Snap-On Keyboard Adds LTE-M and GPS
LILYGO's T-Display K230 puts a Kendryte K230 RISC-V chip, 1GB of RAM, a 4.1-inch AMOLED, LoRa, Wi-Fi, Ethernet and HDMI in a pocket handheld, with an optional keyboard base that holds two 21700 batteries and an nRF9151 cellular and GNSS radio. The kit is about $150 on LILYGO's store.
Most pocket LoRa messengers, LILYGO’s own T-Deck line included, run on an ESP32 and stop at microcontroller firmware. This one runs Linux. That’s the difference worth the headline, and the table makes it plain:
| T-Display K230 | T-Deck Pro | T-Deck-MAX | ClockworkPi uConsole (R-01) | |
|---|---|---|---|---|
| Processor | Kendryte K230, 1.6GHz RISC-V with RVV 1.0, plus an 800MHz core | ESP32-S3 | ESP32-S3 | RISC-V, 1.0GHz single core |
| Memory | 1GB LPDDR4 | 8MB PSRAM | Not compared | 1GB DDR3 |
| Screen | 4.1-inch 568 × 1232 AMOLED touch | 3.1-inch 320 × 240 e-paper | 320 × 240 e-paper | 5.0-inch 720p IPS |
| LoRa | SX1262 or LR2021 | SX1262 | SX1262 | Not listed |
| Cellular | Optional nRF9151 keyboard: LTE-M, NB-IoT, GNSS | Optional A7682E 4G | A7682E 4G built in | Optional 4G LTE module |
| Power | Two 21700 holders on the keyboard base | 1,400mAh battery | 1,400mAh battery | 18650 cells, not included |
| Wired | 10/100 Ethernet, HDMI up to 1080p30, 3 × USB-C | Not compared | Not compared | Not compared |
CNX Software’s Debashis Das got the prices from LILYGO’s store: about $150 for the kit, $98.79 for the bare board, and $70.94 for the keyboard without the nRF9151 or $113.25 with it. On AliExpress the kit is about $180, and in his words “the keyboard adds $133, assuming it is with the nRF9151 at that price.”
The main unit is 104 × 51 × 15.5mm as a bare board, about 110 × 58 × 30mm in its case. It has a 2MP camera that rotates, an H.264/H.265 video engine, Wi-Fi 4, two MMCX antenna jacks, a 40-pin GPIO header and a Qwiic port. Bluetooth LE comes from an nRF52840 on the expansion board. The keyboard connects by a 24-pin connector and carries a BQ25896 charger and BQ27220 fuel gauge for its two 21700 cells.
Das places it next to the CanMV-K230 from 2023, the same chip on a board that “comes in a conventional development board form factor rather than a handheld design.”
What they didn’t say. The headline apps are still marked beta. LILYGO’s GitHub README lists “Beta apps: Meshtastic, LoRaWAN, Xiaozhi voice assistant, PicoClaw, nRF9151 cellular/GNSS data tools, and nRF52840 UART DFU,” and CNX describes the Meshtastic and LoRaWAN support as “experimental.” The same README says “NES ROM files and offline map tiles are not bundled in the default image,” so the maps a field device wants are a separate job. There’s no battery-life figure for either the handheld or the keyboard pair.
What it means for people who run networks. A RISC-V Linux box with an Ethernet jack, HDMI and LoRa is a pocket diagnostic terminal that can also bridge a Meshtastic mesh to a wired network. The catch is that Meshtastic on Linux is the beta part, so anyone planning on it for a deployment should test the build they get, not the feature list.
Why now. LILYGO already sells the ESP32-based T-Deck Pro and T-Deck-MAX to the Meshtastic crowd, and ClockworkPi’s uConsole proved there’s a market for keyboard Linux handhelds. The K230 is LILYGO combining the two.
The open question is time on battery. Two 21700 cells are a lot of capacity for a handheld, and nobody has said yet how long a K230 with the screen, LoRa and the cellular modem all on will last on them.
