Embedded and hobbyist electronics specialist LILYGO has introduced a raft of recent microcontroller growth boards, every concentrating on completely different niches: a low-frequency LoRa board, an ultra-widescreen show board, a LoRa-equipped ePaper show board, and a CAN bus board.
The 4 new entries in LILYGO’s portfolio of gadgets, dropped at our consideration by Linux Gizmos, are: the T-Beam BPF, a compact battery-powered board constructed round an Espressif ESP32-S3 microcontroller and Semtech SX1278 LoRa transceiver; the T-Show Bar, which places the Espressif ESP32-S3 to work driving an on-board ultra-widescreen 2.25″ full-color capacitive show; the T-Mini ePaper S3 with a 1.02″ electrophoretic show and LoRa transceiver; and the T-2CAN, designed for CAN bus work.

The T-Beam BPF, to begin with, affords two Tensilica Xtensa LX7 cores working at as much as 240MHz, 8MB of pseudo-static RAM (PSRAM), and 16MB of program flash, plus a battery holder on the rear linked in to a X-Powers AXP2101 energy administration chip. There is a 128×64 0.96″ OLED show on the prime, plus on-board Quectel L76K International Navigation Satellite tv for pc System (GNSS) receiver and Semtech SX1278 LoRa transceiver — however these in search of compatibility with present LoRa setups might want to take care, as this explicit board makes use of the longer-rage lower-frequency 144–148MHz frequency band moderately than the extra standard 868MHz and 915MHz bands.
The T-Show Bar is a gumstick-style growth board whose footprint is designed to cover behind an ultra-widescreen 2.25″ full-color RGB IPS LCD capacitive touchscreen show with a 76×284 decision, related over an SPI bus to the Espressif ESP32-S3 behind. Elsewhere within the board is a Bosch Sensortech BHI260AP “good sensor” inertial measurement unit (IMU), which features a machine studying core designed for on-sensor exercise detection with out involving the host processor.
The T-Mini ePaper S3 is sort of sure to finish up as a goal gadget for the community-driven Meshtastic mesh community challenge, that includes a compact design with a power-sipping 1.02″ 128×80 monochrome electrophoretic show — sunlight-readable and requiring energy solely when altering states. Contained in the housing is one other ESP32-S3, naturally, plus a battery holder, whereas there is a Semtech SX1262 LoRa transceiver for connectivity and a holder for an 18350-format battery — not equipped with the package.

Lastly, the T-2CAN affords — what else? — an Espressif ESP32-S3 microcontroller on a board devoted to automotive and industrial CAN bus tasks. The board hosts a Microchip MCP2515 CAN bus controller, offering assist for 2 CAN v2.0B connections at charges of as much as 1Mb/s with six 29-bit filters and two 29-bit masks. There is a USB Sort-C connector for knowledge and energy, plus screw terminals for a 5–12VDC energy enter.
All fashions at the moment are listed on the LILYGO retailer, although most had been displaying as out of inventory on the time of writing. The T-Beam BPF is priced at $56.34; the T-Show Bar at $27.36; the T-Mini ePaper S3 at $40.81; and the T-2CAN at $24.36.
