Emblem aka BTA
Tenstaana came up with Emblem aka BTA, another feature-rich monoblock design.
Published September 9, 2022
The great and notoriously prolific tenstaana came up with Emblem aka BTA ("Better Than Alice") – another feature-rich monoblock angled split keyboard.
After the SkyllaBallz, all the split Chunkies, Rocksolid and UniChunky, tenstaana aka freznel keeps raising the bar by his latest project featuring a gorgeous alu case, circular display, scroll ring, combined encoder/5-way switch – and more.
Honestly, this is the level where impostor syndrome starts to kick in when I realize I'm reporting on a project I can't fully fathom. Nevertheless, here are the specs as told by the designer himself:
Specs
- QMK RP2040 powered
- No diodes - uses shift registers (aka tzarc's "SPI" matrix)
- Switch support - MX, Choc V1 and V2
- Pointing devices - PMW3360 or 3389, Cirque trackpad
- Encoders/multi function switches - Bourns encoders for the scroll ring, two ALPS RKJXT1s ("I love this as it combines a 5 way switch and an encoder")
- Piezo buzzer
- Breakouts for all pins, including a JST SH port following the STEMMA QT pinout for i2c expansion.
- Haptic feedback - onboard DRV2065 connected to a Vybronics 1206 actuator
- RGB screen - GC9A01 (onboard or you could use breakouts from AliExpress)
- Gasket mount alu case (e-white) and sandblasted alu plate.

Display
Freznel has been receiving several questions about the display which is directly soldered to the PCB. He was kind enough to provide some close-ups:
