DrunkDeer has introduced the A75 Ultra HE, a 75% mechanical keyboard built around its second-generation Hall Effect technology. Designed for gamers and competitive players, the keyboard offers high-speed performance, advanced calibration systems, and a design inspired by modern aerospace engineering.
At the center of the A75 Ultra HE is a new Hall Effect chip with 0.5 Gauss resolution. The sensor detects precise changes in magnetic fields, allowing for adjustable actuation points between 0.01 mm and 2.0 mm, with 0.005 mm accuracy. It supports magnetic field ranges from 200 to 5000 Gauss and is engineered to remain stable under temperature shifts, hardware aging, and assembly variances. Power consumption is kept to a minimum, with standby draw measured at 0.0001mA.
The keyboard’s Rapid Trigger function registers keypresses on initial press and resets as soon as the key is released. This feature reduces input delay and allows faster keystroke cycles. In addition, Dual Trigger technology enables separate actions to be assigned to the press and release of the same key, expanding functionality for gaming and macros.
To maintain consistent operation over time, the A75 Ultra HE uses an auto-calibration system that performs up to 8000 recalibrations per second. This process adjusts for changes in magnetic sensitivity, switch wear, and minor assembly differences, ensuring a uniform typing experience.
The keyboard supports an 8 kHz polling rate, achieving a response time of 0.2 milliseconds from key actuation to system recognition. It also includes a Dual-Solution mode, giving users the option to switch between Soft Bounce and Firm Bottom-Out keyfeel profiles depending on personal preference.
The A75 Ultra HE’s design features PVD chrome-plated panels, sharp contours, and an “A” metal control knob symbolizing its ACE branding. Custom keycaps with Morse code engravings provide a distinctive visual detail, while the full 360-degree aesthetic is intended to complement high-end gaming setups.
DrunkDeer has opened pre-orders for the A75 Ultra HE in two color variants, Ignite and Tourmaline, at a price of $219 USD.
